5-Methyl-1,3-benzenedicarboxylic acid

Description:

5-Methyl-1,3-benzenedicarboxylic acid, also known as isophthalic acid methyl derivative, is an aromatic dicarboxylic acid characterized by the presence of two carboxylic acid groups (-COOH) attached to a benzene ring, along with a methyl group (-CH3) at the 5-position. This compound is typically a white crystalline solid with a high melting point and is soluble in polar solvents such as water and alcohols. It exhibits properties typical of dicarboxylic acids, including the ability to form esters and amides, making it useful in various chemical syntheses. The presence of the methyl group influences its reactivity and solubility compared to other isomers. 5-Methyl-1,3-benzenedicarboxylic acid is utilized in the production of polymers, resins, and as an intermediate in organic synthesis. Its chemical structure allows for potential applications in the development of materials with specific thermal and mechanical properties. Safety data indicates that, like many organic acids, it should be handled with care to avoid irritation or adverse reactions.
