Description

Terephthalic acid is a dicarboxylic acid that is used as a monomer in the production of polyesters. It is produced by the oxidation of p-hydroxybenzoic acid with aqueous sodium hydroxide. The reaction solution of terephthalic acid and glycol ethers contains water vapor and glycol esters, which are formed during the reaction. This product has been shown to inhibit drugs such as acetylcholinesterase and butyrylcholinesterase, which are important for the treatment of Alzheimer's disease and other neurological disorders. Terephthalic acid can be used as a fluorescence probe for determination of redox potential in analytical methods such as cyclic voltammetry, or to determine human serum levels in clinical analysis. Structural analyses have revealed intramolecular hydrogen bonds between the carboxyl groups and phenolic hydroxyl groups in terephthalic acid.
