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.

Terephthalaldehyde chloride is a water-insoluble, white solid that is soluble in organic solvents. It forms a protective layer on metal surfaces and plastics, preventing corrosion and microbial growth. Terephthalaldehyde chloride has been shown to be effective against Escherichia coli, Klebsiella pneumoniae, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, and Salmonella enterica. Terephthalaldehyde chloride's antimicrobial activity is attributed to its acid complex with phosphorus pentoxide and electrochemical impedance spectroscopy data indicate that it reacts with the anionic sites of bacterial cell walls. Terephthalaldehyde chloride does not react with human serum proteins or ester linkages; however, it has toxic effects on mice at high doses.
