CAS 100-21-0: 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.
