When sourcing chemical intermediates for demanding applications, precision in specifications is non-negotiable. For 4-Bromo-3,5-difluorobenzoic Acid (CAS: 651027-00-8), understanding its typical characteristics ensures that you receive a product fit for purpose, whether for intricate pharmaceutical synthesis or cutting-edge material science research. If you are looking to buy this compound, paying close attention to its specifications is the first step in ensuring quality and reliability.
The primary identifier for this chemical is its CAS Number: 651027-00-8. When you search for this product from various suppliers, you will invariably encounter key specifications that define its quality and suitability for your work. The most critical of these is typically the purity level. For 4-Bromo-3,5-difluorobenzoic Acid, a minimum purity of 97% is commonly cited. This high purity is essential for many synthetic processes, as impurities can lead to side reactions, reduced yields, and compromised final product quality.
Another crucial characteristic is the physical appearance. This compound is consistently described as an off-white solid. Any deviation from this description, such as a distinctly different color or a liquid or crystalline powder form when a solid is expected, should prompt further inquiry. The physical form can sometimes indicate storage issues or potential contamination.
Beyond purity and appearance, other technical data provided by a manufacturer can be informative. While not always listed on product pages, details such as melting point (typically around 181-185℃) and molecular weight (237.00 g/mol) are important for chemists to perform calculations and understand the compound's behavior under different conditions. Storage recommendations, usually involving cool, dry conditions in a sealed container, are also vital for maintaining the integrity of the product over time.
When you buy 4-Bromo-3,5-difluorobenzoic Acid, particularly from international manufacturers like those found in China, ensure you request a Certificate of Analysis (CoA). This document will detail the exact specifications met by the batch you receive, including purity, assay results, and potentially other analytical data. This is your assurance of quality and consistency, vital for both research and industrial production. Reliable suppliers will readily provide this documentation and can discuss pricing and availability for your specific needs.
