For procurement specialists and R&D scientists, the quality and specifications of chemical intermediates are paramount. This article focuses on 4-Bromo-2-Fluoro-6-Nitrophenol (CAS 320-76-3), detailing the essential quality control measures and specifications that buyers should look for when sourcing from manufacturers, particularly those in China.

The integrity of a synthesis process often hinges on the purity and consistency of its starting materials. When a buyer decides to buy 4-Bromo-2-Fluoro-6-Nitrophenol, they are looking for a reliable chemical that will perform predictably. The standard quality benchmarks for such intermediates often include adherence to pharmacopoeial standards like USP (United States Pharmacopeia), BP (British Pharmacopoeia), and FCC (Food Chemicals Codex). A reputable manufacturer will clearly state which standards their product meets.

Key specifications for 4-Bromo-2-Fluoro-6-Nitrophenol typically include its physical appearance, which is often described as a red powder. Beyond visual inspection, assay or purity levels are critical. High purity ensures that side reactions are minimized, leading to better yields and cleaner final products. Manufacturers will provide a Certificate of Analysis (CoA) that details these specifications, including parameters such as moisture content, heavy metal limits, and the percentage of the active compound. Understanding these details is vital for formulators and researchers.

Beyond standard purity, manufacturers may also offer specific grades of 4-Bromo-2-Fluoro-6-Nitrophenol tailored to different applications. For example, a pharmaceutical intermediate grade will have stricter impurity profiles than a general industrial grade. When inquiring about the price of CAS 320-76-3, it is important to clarify which grade is being offered and what quality assurance measures are in place. This transparency is a hallmark of a trustworthy supplier.

Choosing a manufacturer with robust quality control systems is essential for ensuring supply chain stability and product integrity. When looking for a chemical intermediate supplier in China, inquire about their quality management certifications (e.g., ISO), their analytical methods for testing, and their batch traceability procedures. By prioritizing these quality aspects, businesses can confidently procure 4-Bromo-2-Fluoro-6-Nitrophenol, ensuring the success of their manufacturing and research endeavors.
