CAS 4741-53-1

Tetraphenylphthalic anhydride

Description:

Tetraphenylphthalic anhydride, with the CAS number 4741-53-1, is an organic compound characterized by its structure, which includes four phenyl groups attached to a phthalic anhydride moiety. This compound typically appears as a white to light yellow crystalline solid and is known for its high melting point and low solubility in water, making it more soluble in organic solvents such as benzene and toluene. It is primarily utilized in the synthesis of various polymers and as a reagent in organic chemistry, particularly in the preparation of polyimides and other high-performance materials. Tetraphenylphthalic anhydride exhibits properties such as thermal stability and the ability to undergo reactions typical of anhydrides, including hydrolysis and nucleophilic attack. Additionally, it can act as a cross-linking agent in resin formulations, enhancing the mechanical properties of the resulting materials. Safety precautions should be observed when handling this compound, as it may pose health risks if inhaled or ingested.
