In the intricate world of pharmaceutical manufacturing, the selection of high-quality intermediates is paramount. Among these critical compounds, 5-Nitrosalicylic Acid (CAS 96-97-9) stands out as an indispensable building block, particularly for the synthesis of Mesalamine, a widely used Active Pharmaceutical Ingredient (API). As a leading manufacturer and supplier, we understand the significance of this compound and are dedicated to providing pharmaceutical companies with a reliable source for their critical needs.

5-Nitrosalicylic Acid, also known by its IUPAC name 2-hydroxy-5-nitrobenzoic acid, is characterized by its distinct yellow crystalline powder appearance and a purity level that typically reaches ≥98%. Its chemical structure, featuring both a nitro group and a hydroxyl group on a benzoic acid core, imparts unique reactivity and functionality, making it ideal for complex organic syntheses. The melting point, often cited around 226-229°C, further underscores its stable chemical nature, crucial for consistent process outcomes.

The primary role of 5-Nitrosalicylic Acid in the pharmaceutical sector is its function as a key intermediate in the production of Mesalamine. Mesalamine, also known as 5-aminosalicylic acid, is an anti-inflammatory drug extensively used in the treatment of inflammatory bowel diseases like ulcerative colitis and Crohn's disease. The precise synthesis pathway of Mesalamine relies heavily on the quality and purity of its precursor, 5-Nitrosalicylic Acid. Sourcing this intermediate from a reputable manufacturer ensures that the final API meets stringent quality standards, thereby guaranteeing the safety and efficacy of the therapeutic agent for patients.

Beyond its critical role in Mesalamine synthesis, 5-Nitrosalicylic Acid exhibits versatility that extends to other chemical applications. It is utilized in analytical chemistry as a reagent for colorimetric determination, aiding in the precise measurement of amino acids and proteins. Furthermore, its structural properties make it a valuable dye intermediate, contributing to the development of various colorants. In industrial settings, it also finds application as a corrosion inhibitor, protecting metal surfaces from degradation.
