Isophthalic acid

Description:
Isophthalic acid, with the CAS number 121-91-5, is a colorless crystalline organic compound classified as a dicarboxylic acid. It is an isomer of phthalic acid, distinguished by the positioning of its carboxyl groups on the benzene ring. Isophthalic acid is known for its moderate solubility in water and good solubility in organic solvents such as ethanol and acetone. It has a melting point that typically ranges around 300°C and is stable under normal conditions. This compound is primarily used in the production of polyesters, particularly in the manufacture of high-performance plastics and resins, due to its ability to enhance thermal stability and mechanical properties. Additionally, isophthalic acid serves as a building block in the synthesis of various dyes and pharmaceuticals. Its chemical formula is C8H6O4, and it exhibits properties typical of aromatic dicarboxylic acids, including the ability to undergo esterification and polymerization reactions.
