In the rigorous world of pharmaceutical synthesis, the precise specifications of raw materials and intermediates are paramount. For compounds like 2-Bromo-5-fluoro-4-methyl-3-nitropyridine (CAS: 917918-84-4), understanding and meeting these specifications is crucial for reproducible results and the successful development of APIs. At NINGBO INNO PHARMCHEM CO.,LTD., we prioritize delivering intermediates that meet the highest industry standards. This article outlines the key specifications that procurement managers and research chemists should focus on when looking to buy this vital compound.

Purity Level: The Non-Negotiable Standard

The most critical specification for any pharmaceutical intermediate is its purity. For 2-Bromo-5-fluoro-4-methyl-3-nitropyridine, a purity of ≥98.0% is typically required. This high level of purity ensures that the desired chemical transformations occur efficiently and that unwanted side reactions, which could generate impurities in the final API, are minimized. A reliable manufacturer will provide a detailed Certificate of Analysis (CoA) confirming this purity, often determined by High-Performance Liquid Chromatography (HPLC) or Gas Chromatography (GC).

Appearance: A Visual Indicator of Quality

The physical appearance of the compound can offer initial insights into its quality. 2-Bromo-5-fluoro-4-methyl-3-nitropyridine is typically described as a White Crystalline Powder. Deviations from this description, such as discoloration or the presence of foreign particulate matter, might indicate issues with manufacturing, handling, or storage. As a trusted supplier, we ensure our products are consistently presented in their optimal physical form.

Molecular Formula and Weight: Verifying Identity

Confirming the correct molecular formula (C6H4BrFN2O2) and molecular weight (235.01100) is fundamental. These values are essential for stoichiometric calculations in synthesis reactions. While these are inherent properties, ensuring they align with the product's CAS number (917918-84-4) is a basic but important verification step.

Storage Conditions: Maintaining Integrity

Proper storage is vital to maintain the integrity and shelf-life of chemical intermediates. The recommendation to 'Store in a tightly closed container. Store in a cool, dry' environment is standard for many sensitive organic compounds. Following these guidelines helps prevent degradation due to moisture or temperature fluctuations, ensuring the product remains viable for use. We provide clear storage recommendations with our products.

When you are ready to purchase 2-Bromo-5-fluoro-4-methyl-3-nitropyridine, remember to scrutinize the specifications provided by the manufacturer. Focusing on purity, appearance, and adherence to proper storage conditions will help ensure the success of your pharmaceutical synthesis projects.
