2-Bromopyridine-5-carbaldehyde, identified by CAS 149806-06-4, is a brominated pyridine aldehyde used as a versatile intermediate in medicinal chemistry, pharmaceutical research, and advanced organic synthesis. At Maison Chemical, I help B2B buyers evaluate this compound by connecting its verified identity, project requirements, documentation needs, and supply conditions before quotation. The molecular formula is commonly represented as C6H4BrNO, with a calculated molecular weight of approximately 186.01 g/mol. Because commercial specifications can differ by production route, packaging, and quality agreement, I recommend confirming every critical parameter against the supplier’s current specification and lot documentation.

I prepared this guide for procurement teams, process chemists, medicinal chemistry groups, pharmaceutical intermediate buyers, and distributors evaluating 2-Bromopyridine-5-carbaldehyde for laboratory or manufacturing use. It is also relevant to organizations that need a dependable source before moving from milligram-scale screening to gram- or kilogram-scale purchasing. The guide focuses on practical supplier communication rather than treating a general catalog description as a complete quality specification.
2-Bromopyridine-5-carbaldehyde contains two important functional features: a bromine substituent on a pyridine ring and an aldehyde group. The aldehyde can participate in transformations such as condensation and reductive amination, while the aryl bromide may provide a handle for further cross-coupling or other substitution chemistry, depending on the selected reaction conditions. These functions make the compound useful for building structurally diverse heteroaromatic intermediates.
The CAS number 149806-06-4 is an essential identity reference, but it should not be the only control used during purchasing. I advise buyers to compare the CAS number with the chemical name, molecular formula, molecular weight, structural representation, and supplier-specific product code. If the material will enter a regulated or tightly controlled process, identity confirmation and lot-specific analytical documentation should be reviewed before release.
A useful specification should distinguish between fixed identity information and variable release criteria. Identity data generally includes the product name, CAS number, molecular formula, molecular weight, and appearance description. Release criteria may include assay, water content, residual solvents, related substances, residue on ignition, and analytical identification, but the acceptable limits must be agreed between buyer and supplier rather than assumed from a generic product page.
| Specification Area | What the Buyer Should Confirm |
|---|---|
| Identity | CAS 149806-06-4, chemical name, formula C6H4BrNO, and approximate molecular weight of 186.01 g/mol |
| Appearance | Supplier’s current description, physical form, and any storage-related observations |
| Assay and purity | Test method, acceptance limit, chromatographic basis, and lot-specific result |
| Impurity profile | Related substances, residual solvents, and process-specific impurities where relevant |
| Documentation | Certificate of analysis, safety data sheet, batch information, and agreed quality documents |
| Packaging | Container type, net quantity, labeling, protection from light or moisture where applicable |
A catalog specification describes the intended product, while a certificate of analysis describes a particular batch. I recommend requesting the latest available COA or a representative quality document during technical evaluation, then confirming that the final shipment will include batch-specific results. This approach helps buyers compare suppliers on measurable evidence instead of relying only on a nominal purity statement.
For medicinal chemistry, this intermediate may be selected when a project requires a brominated pyridine scaffold with an aldehyde functionality available for downstream elaboration. In route development, the buyer should evaluate not only chemical suitability but also how the material behaves in the planned reaction sequence. A small-scale compatibility experiment can help confirm whether the supplier’s material is suitable for the intended solvent, catalyst, base, temperature, and work-up conditions.
For pharmaceutical intermediate development, documentation and repeatability become increasingly important as the process moves toward scale-up. Buyers may need controlled impurity information, consistent packaging, traceability, and a defined change-notification process. For research distribution, flexibility in pack size and a clear lead-time estimate may be more important than a highly customized quality agreement.
In practice, buyers may encounter research-grade, standard commercial, or project-specific material presentations. These labels are not interchangeable with a universally defined regulatory grade, so I advise asking what each designation means in measurable terms. The relevant questions include the assay method, analytical acceptance criteria, packaging configuration, availability of a COA, and whether the material is produced as a standard item or made against a specific order.
Some projects require only identity and purity confirmation, while others require a broader analytical package. Depending on the application, a buyer may request chromatographic data, spectroscopic support, water or residual-solvent information, and a defined retest or storage statement. Maison Chemical can discuss the appropriate document package according to the application, destination market, and purchasing stage.

I first ask buyers to define the intended use, target quantity, required delivery region, and minimum documentation. The request should state whether the material is for route scouting, process development, analytical work, or commercial intermediate production. It should also identify any restrictions on solvents, impurities, packaging, or shipping classification.
Next, I recommend checking whether each quotation refers to the same CAS number and structure. Buyers should compare the stated formula and molecular weight, then review the proposed assay method and available analytical records. If a supplier cannot clearly explain the test basis or provide a representative COA, the buyer should treat the quotation as incomplete rather than comparing price alone.
Commercial evaluation should cover requested quantity, available pack sizes, MOQ, production or preparation lead time, payment terms, Incoterms, packaging, and destination requirements. MOQ and lead time are not universal properties of CAS 149806-06-4; they depend on stock status, order size, production scheduling, and export arrangements. I therefore provide these details through a project-specific quotation instead of publishing unsupported fixed promises.
Before purchase order approval, I suggest agreeing on the required documents and release process. This may include a COA, SDS, packing information, batch or lot identification, and any additional analytical records defined in the buyer’s quality procedure. Early alignment reduces the risk of receiving material that is chemically suitable but administratively difficult to release.
The final price for 2-Bromopyridine-5-carbaldehyde normally reflects quantity, availability, packaging, analytical requirements, destination, and shipping conditions. Small research quantities may have a higher unit cost because packaging and handling represent a larger proportion of the order. Larger requirements may require production planning, so buyers should provide an estimated annual demand or phased delivery schedule when possible.
I recommend requesting a quotation with at least four commercial data points: required quantity, target delivery date, destination country, and documentation expectations. For urgent projects, the buyer should ask whether the quoted material is available from existing stock or requires preparation. A clear distinction between stock supply and scheduled production gives the purchasing team a more realistic view of delivery risk.
When I evaluate a potential supply source, I look for transparent product identification, a documented quality approach, responsive technical communication, and a practical export process. I also check whether the supplier can explain its available pack sizes, expected lead time, packaging method, and document availability without making absolute claims that cannot be verified. This evaluation is especially important when the material will be used repeatedly across multiple development batches.
Maison Chemical supports B2B inquiries for 2-Bromopyridine-5-carbaldehyde CAS 149806-06-4 by reviewing the buyer’s specifications and preparing a quotation around the actual project requirement.
