CAS 552-30-7

Trimellitic anhydride

Description:

Trimellitic anhydride (TMA) is a chemical compound with the CAS number 552-30-7, characterized by its anhydride functional group derived from trimellitic acid. It appears as a white to light yellow crystalline solid and is known for its high reactivity, particularly with alcohols and amines, which allows it to form esters and amides. TMA is primarily used in the production of polyesters, plasticizers, and resins, contributing to the enhancement of material properties such as flexibility and durability. It has a relatively high melting point and is soluble in organic solvents like acetone and toluene, but insoluble in water. Due to its reactivity, TMA can pose health risks, including respiratory irritation and skin sensitization, necessitating careful handling and appropriate safety measures in industrial applications. Additionally, it is important to note that TMA can undergo hydrolysis in the presence of moisture, leading to the formation of trimellitic acid. Overall, trimellitic anhydride is a versatile compound with significant industrial applications, particularly in the field of polymer chemistry.
