4-(N-Boc-amino)phenylboronic acid CAS 380430-49-9: A Buyer’s Guide to Specifications, COA, Packaging, and Bulk Supply

If you are sourcing 4-(N-Boc-amino)phenylboronic acid, CAS 380430-49-9, I recommend evaluating four items before placing an order: confirmed identity, lot-specific quality documentation, packaging suitability, and the supplier’s ability to support your required quantity and delivery schedule. The compound is an aryl boronic acid building block with a protected amino group, commonly considered for research, medicinal chemistry, and pharmaceutical intermediate applications. Its commonly reported molecular formula is C₁₁H₁₆BNO₄, with a calculated molecular weight of approximately 237.06 g/mol; buyers should confirm these values against the supplier’s current specification and analytical records.

At Maison Chemical, I help B2B customers review product specifications, request a batch-specific COA, select practical packaging, and discuss sample, pilot, or bulk supply requirements. Because quality expectations can differ between discovery research and process development, I do not recommend choosing a supplier based on price alone.

Key Takeaways for Buyers

• Verify the product name, CAS number 380430-49-9, molecular formula, molecular weight, and structure before technical approval.
• Request a COA for the actual batch, including assay, appearance, water or moisture information where applicable, and analytical methods.
• Match packaging to the order size, handling environment, storage conditions, and expected consumption rate.
• Ask for clear information on MOQ, sample availability, lead time, export documentation, and custom procurement support.
• Use a written specification and an agreed acceptance standard when comparing suppliers.

Who This Buyer’s Guide Is For

This guide is intended for procurement teams, laboratory managers, research chemists, pharmaceutical intermediate buyers, contract development organizations, and distributors evaluating 4-(N-Boc-amino)phenylboronic acid. It is also useful when a project is moving from small-scale screening to route development and the purchasing team needs more than a catalog listing. I focus on practical questions that affect approval, shipment, receiving inspection, and future replenishment.

The compound may be listed under several naming variations, including 4-(N-Boc-amino)phenylboronic acid and 4-(tert-butoxycarbonylamino)phenylboronic acid. Naming variations should not replace identity confirmation, because similar aryl boronic acid intermediates can have different substitution patterns and performance in a synthetic route. I recommend checking the CAS number, structure, formula, molecular weight, and analytical data together.

Basic Product Context and Core Function

4-(N-Boc-amino)phenylboronic acid contains two important functional elements: a boronic acid group and a Boc-protected amino group. The boronic acid can participate in palladium-catalyzed cross-coupling chemistry, including Suzuki-type reactions, while the Boc group is used as a temporary protecting group for the amino functionality. This combination makes the material relevant to the preparation of substituted aromatic intermediates and research compounds.

The Boc group can help control the reactivity of the amino group during selected synthetic steps, but its suitability depends on the complete reaction sequence and deprotection conditions. I therefore treat this material as a route-specific intermediate rather than a universally interchangeable raw material. The final selection should be confirmed by the customer’s chemist using the intended reaction conditions and impurity tolerance.

Specifications Buyers Should Review

Identity and Chemical Information

A basic technical review should include the product name, CAS number, molecular formula, molecular weight, structural representation, and lot or batch number. For CAS 380430-49-9, a commonly reported molecular weight is approximately 237.06 g/mol, but the value should be checked against the supplier’s controlled documentation. If your purchasing system requires a defined naming convention, ask the supplier to align the commercial specification with your internal material master.

Identity testing may include techniques such as nuclear magnetic resonance, mass spectrometry, infrared spectroscopy, or chromatography, depending on the supplier’s quality system and product stage. I recommend asking which test is used for identity confirmation and whether the reported result is linked to the supplied batch. A generic analytical statement is less useful than a batch-specific result with a defined method.

Purity, Appearance, and Related Information

Buyers should review the stated assay or purity requirement, appearance description, residual solvents, water or moisture content, and related substances when these parameters are relevant to the application. Do not assume that a high assay value automatically means the material will perform identically in every coupling reaction, because particle properties, handling history, and trace impurities may also influence process behavior. The acceptance limits should be agreed before purchase, especially for scale-up work.

For research quantities, a standard specification may be sufficient if the material is being used for early screening. For process development or regulated supply chains, I recommend requesting a more detailed specification that identifies test methods, reporting units, acceptance limits, retest or review information, and storage guidance. Maison Chemical can review these requirements before quotation so that the commercial offer is aligned with the intended use.

How to Evaluate the COA

A certificate of analysis should be connected to the exact batch supplied, not only to the product name. I recommend checking the COA number, batch number, manufacturing or test date where provided, specification limits, actual results, analytical methods, and authorized approval. The document should clearly identify the material as 4-(N-Boc-amino)phenylboronic acid, CAS 380430-49-9.

Before approval, compare the COA with your purchase specification and intended use. For example, if residual solvents are important to your process, confirm that they are included or ask whether a separate statement is available. If a customer requires a particular testing method, such as HPLC or NMR, that requirement should be discussed before production or shipment rather than after delivery.

With competitive price and timely delivery, Maison Chemical sincerely hope to be your supplier and partner.

Questions to Ask About COA Documentation

• Is the COA issued for the actual shipment batch?
• Are assay and related-substance results reported with units and acceptance limits?
• Which analytical methods are used, and are chromatograms or spectra available when required?
• Does the document identify storage conditions and a retest or review date if applicable?
• Can the supplier provide supporting documents for export, customs, or internal quality review?

Packaging, Storage, and Shipping Considerations

Packaging should be selected according to quantity, transport distance, customer handling procedures, and the material’s documented storage guidance. Common commercial approaches may include a sealed inner container with an appropriate outer package, but the exact configuration should be confirmed in the quotation and shipping documents. I do not recommend relying on an assumed package size or storage condition when your site has specific receiving requirements.

For a small research order, a package of 100 g may be operationally convenient, while pilot or manufacturing needs may require larger units or multiple containers. These quantities are examples for planning only, not a guaranteed standard pack. Buyers should confirm net weight, container material, tamper evidence, labeling language, lot traceability, and whether the packaging is suitable for the expected transit conditions.

Because boronic acid intermediates can be sensitive to handling and environmental exposure depending on their form and formulation, the supplier’s product-specific storage instruction should take priority. I recommend keeping the original label and batch documentation with the material and recording receipt condition during incoming inspection. Any damaged package, discrepancy in weight, or mismatch between label and COA should be reported before use.

Bulk Supply, MOQ, and Lead-Time Planning

Bulk sourcing is not simply a request for a larger quantity. It requires confirmation of available inventory, production capacity, batch size, packaging format, quality release timing, and export logistics. MOQ and lead time can vary with the requested purity, documentation package, packaging configuration, and whether the material is available from stock or requires planned production.

For this reason, I recommend sending a structured inquiry that includes the required quantity, target delivery country, desired specification, packaging preference, end-use category, and requested documents. A clear inquiry allows Maison Chemical to respond with a more useful quotation rather than a price detached from supply conditions. If your project has a fixed manufacturing date, include the required arrival date and allow time for quality review and transportation.

Supplier Evaluation Checklist

1. Confirm the supplier can identify the product by CAS number 380430-49-9 and provide consistent technical information.
2. Request a current specification and a representative or batch-specific COA for review.
3. Clarify whether samples, pilot quantities, and bulk quantities are supported.
4. Ask about MOQ, production lead time, stock status, packaging, and shipping terms.
5. Review communication speed, document accuracy, and ability to address non-standard requirements.
6. Agree on acceptance criteria before issuing a purchase order.

Common Purchasing Mistakes

One common mistake is comparing suppliers only by price per kilogram without comparing assay limits, documentation, packaging, and delivery basis. Another is accepting a general COA template without confirming that the supplied batch will receive the same testing and documentation. I also advise buyers not to assume that a catalog quantity represents continuous bulk availability.

A further risk is failing to distinguish sample approval from commercial qualification. A sample can support route screening, but a larger order may involve different batch timing, packaging, and release procedures. If the material is intended for a critical intermediate, qualify the supplier using a written specification and a defined incoming-testing plan.
