4-Hydroxyisophthalic acid

Description:
4-Hydroxyisophthalic acid, with the CAS number 636-46-4, is an aromatic dicarboxylic acid characterized by the presence of two carboxylic acid groups (-COOH) and a hydroxyl group (-OH) attached to a benzene ring. This compound is a derivative of isophthalic acid, where the hydroxyl group is positioned at the 4-position relative to one of the carboxylic acid groups. It typically appears as a white crystalline solid and is soluble in polar solvents such as water and alcohols. The presence of both carboxylic acid and hydroxyl functional groups allows for versatile reactivity, making it useful in the synthesis of polyesters and other polymers. Additionally, 4-hydroxyisophthalic acid can serve as a building block in the production of various materials, including resins and coatings, due to its ability to enhance thermal stability and mechanical properties. Its applications extend to the fields of materials science and organic synthesis, where it plays a role in developing advanced materials with specific functional characteristics.
