Terephthalic acid

Description:

Terephthalic acid, with the CAS number 100-21-0, is a white crystalline solid that is primarily used as a precursor in the production of polyethylene terephthalate (PET), a widely used polymer in textiles and plastic bottles. It is an aromatic dicarboxylic acid, characterized by its two carboxyl (-COOH) functional groups attached to a benzene ring. Terephthalic acid is sparingly soluble in water but soluble in organic solvents such as ethanol and acetone. It has a melting point that typically falls within a specific range, indicating its stability under various conditions. The compound is known for its high thermal stability and resistance to degradation, making it suitable for high-temperature applications. Additionally, terephthalic acid can undergo various chemical reactions, including esterification and polymerization, which are essential for its role in producing synthetic fibers and plastics. Safety data indicates that it should be handled with care, as it may cause irritation upon contact with skin or eyes.

Terephthalic acid

CAS: 100-21-0

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.
