Product Description:

3-Amino-4-hydroxybenzoic acid is an aromatic compound featuring both an amino group and a hydroxyl group ortho to a carboxylic acid. It serves as a versatile chemical building block, particularly valued in pharmaceutical synthesis. Its primary industrial application is as a key intermediate in the production of X-ray contrast media agents, such as Iopamidol and Iopromide. These non-ionic, low-osmolar contrast agents are widely used in diagnostic imaging procedures like computed tomography (CT) scans and angiography. The compound's structure allows for further functionalization to create the triiodinated benzene core essential for these agents' radio-opacity. The compound is also utilized in the synthesis of other pharmacologically active molecules and dyes. It requires careful handling as it may cause skin and eye irritation.
