For scientists and procurement specialists in the pharmaceutical and fine chemical sectors, a deep understanding of product specifications is paramount when selecting raw materials. 5-Formyl-2-hydroxybenzoic acid (CAS 616-76-2), a vital intermediate, requires careful attention to its detailed chemical and physical properties to ensure its efficacy in synthesis.

The primary specification for 5-Formyl-2-hydroxybenzoic acid is its purity, typically stated as 98% minimum. This level of purity is critical for pharmaceutical applications, as even minor impurities can lead to unwanted side reactions, reduced yields, and compromised final product quality. R&D chemists often need to buy 5-formyl-2-hydroxybenzoic acid that meets stringent purity requirements for their complex synthetic routes. Therefore, verifying the purity through a reliable Certificate of Analysis (CoA) from the supplier is a non-negotiable step.

Beyond purity, other key physical and chemical properties are important. The molecular formula is C8H6O4, with a molecular weight of approximately 166.13. Its appearance is generally described as a 'Pale beige fine crystalline powder,' which provides a visual indicator for material handling and identification. Understanding its melting point, reported around 250 °C with decomposition, is also crucial for storage and reaction condition considerations. When seeking a CAS 616-76-2 pharmaceutical intermediate price, ensure the quotes are accompanied by comprehensive specification data.

When engaging with a 5-formylsalicylic acid manufacturer, particularly one based in China, it is important to inquire about their quality control measures. A reputable supplier will not only provide precise specifications but also maintain consistency across batches. For those looking to purchase 5-formyl-2-hydroxybenzoic acid in bulk, confirming the supplier's ability to consistently meet these specifications over time is essential for uninterrupted production.

In summary, a thorough understanding of the specifications for 5-Formyl-2-hydroxybenzoic acid, including purity, appearance, molecular weight, and melting point, is fundamental for its successful application in pharmaceutical synthesis. By partnering with knowledgeable suppliers who provide detailed product information, researchers and manufacturers can confidently procure this essential intermediate, ensuring the integrity and efficiency of their chemical processes.
