2-Methyl-1,4-benzenedicarboxylic acid

Description:

2-Methyl-1,4-benzenedicarboxylic acid, also known as isophthalic acid, is an aromatic dicarboxylic acid characterized by its two carboxylic acid functional groups (-COOH) attached to a benzene ring at the 1 and 4 positions, with a methyl group at the 2 position. This compound is a white crystalline solid that is soluble in water and organic solvents like ethanol and acetone. It has a melting point that typically falls within a moderate range, indicating its stability under standard conditions. Isophthalic acid is primarily used in the production of polyesters, particularly in the manufacture of high-performance plastics and resins, as well as in coatings and fibers. Its chemical structure contributes to its ability to enhance the thermal and mechanical properties of polymers. Additionally, it can participate in various chemical reactions, including esterification and polymerization, making it a valuable intermediate in organic synthesis. Safety data indicates that it should be handled with care, as it may cause irritation upon contact with skin or eyes.
