4-tert-Butylphthalic anhydride

Description:
4-tert-Butylphthalic anhydride, with the CAS number 32703-79-0, is an organic compound that belongs to the class of phthalic anhydrides. It is characterized by its anhydride functional group, which is derived from phthalic acid. This compound typically appears as a colorless to pale yellow solid and is known for its high melting point and low solubility in water, making it more soluble in organic solvents such as acetone and toluene. The presence of the tert-butyl group enhances its steric bulk, which can influence its reactivity and interactions with other chemical species. 4-tert-Butylphthalic anhydride is often used as a chemical intermediate in the production of various polymers, resins, and plasticizers, contributing to the enhancement of material properties. Additionally, it may serve as a curing agent in epoxy formulations. Due to its chemical structure, it can undergo hydrolysis to form 4-tert-butylphthalic acid in the presence of moisture. Safety precautions should be observed when handling this compound, as it may cause irritation upon contact with skin or eyes.
