1,4-Benzenedicarboxylic acid, bis(4-hydroxybutyl) ester

Description:

1,4-Benzenedicarboxylic acid, bis(4-hydroxybutyl) ester, commonly known as bis(4-hydroxybutyl) terephthalate, is an organic compound characterized by its ester functional groups derived from terephthalic acid and 4-hydroxybutanol. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its specific form and purity. It is soluble in organic solvents such as ethanol and acetone but has limited solubility in water. The presence of both aromatic and aliphatic structures contributes to its thermal stability and potential applications in polymer chemistry, particularly in the production of polyesters. Additionally, it exhibits good mechanical properties and can be utilized as a plasticizer or in the synthesis of various copolymers. The compound's structure allows for hydrogen bonding, which can influence its physical properties and interactions with other materials. Safety data indicates that, like many organic esters, it should be handled with care to avoid skin and eye contact, and appropriate safety measures should be taken during its use in industrial or laboratory settings.
