Product Description:

5-Nitrosalicylic acid is an organic compound featuring both a carboxylic acid group and a nitro group attached to a benzene ring. It is a yellow crystalline solid with a molecular formula of C7H5NO5. This compound serves as a key intermediate in the synthesis of various pharmaceuticals and dyes. Its primary application is in the production of the anti-inflammatory drug mesalamine (5-aminosalicylic acid), which is used to treat inflammatory bowel diseases such as ulcerative colitis and Crohn's disease. The nitro group in 5-nitrosalicylic acid can be selectively reduced to an amino group to form the active pharmaceutical ingredient. As a bifunctional building block, it is also utilized in organic synthesis and material science research. It is important to handle with care as it may cause skin and eye irritation.
