CAS 100-20-9: Terephthaloyl chloride

Description: Terephthaloyl chloride, with the CAS number 100-20-9, is an aromatic acyl chloride derived from terephthalic acid. It is characterized by its white crystalline solid form and is known for its strong reactivity due to the presence of the acyl chloride functional group. This compound is primarily used as an intermediate in the synthesis of polyesters and polyamides, particularly in the production of high-performance materials such as aramid fibers and thermoplastic elastomers. Terephthaloyl chloride is soluble in organic solvents like dichloromethane and chloroform but is insoluble in water. It is important to handle this substance with care, as it can be corrosive and may cause irritation to the skin, eyes, and respiratory system. Additionally, it can react violently with water, releasing hydrochloric acid, which necessitates appropriate safety precautions during its use and storage. Overall, terephthaloyl chloride plays a significant role in the chemical industry, particularly in the development of advanced polymeric materials.
