CAS 29278-69-1: 1,4-Benzenedicarboxylic acid, 1,4-butanediyl ester
Description:1,4-Benzenedicarboxylic acid, 1,4-butanediyl ester, commonly known as butylene terephthalate, is an organic compound characterized by its ester functional groups derived from terephthalic acid and butanediol. It appears as a colorless to pale yellow solid and is soluble in organic solvents such as acetone and ethyl acetate, but has limited solubility in water. This compound is primarily used in the production of polyesters and as a plasticizer, enhancing the flexibility and durability of polymer materials. Its chemical structure features two carboxylic acid groups attached to a benzene ring, which contributes to its reactivity and ability to form various polymeric materials. Additionally, it exhibits thermal stability and good mechanical properties, making it suitable for applications in textiles, packaging, and automotive components. Safety data indicates that while it may cause irritation upon contact with skin or eyes, it is generally considered to have low toxicity. Proper handling and storage are recommended to ensure safety and maintain its integrity for industrial use.
