CAS 4808-48-4

Diphenylmaleic anhydride

Description:

Diphenylmaleic anhydride, with the CAS number 4808-48-4, is an organic compound characterized by its anhydride functional group and the presence of two phenyl groups attached to a maleic anhydride backbone. This compound typically appears as a white to light yellow crystalline solid and is known for its high melting point and stability under normal conditions. It is soluble in organic solvents such as acetone, chloroform, and benzene, but is generally insoluble in water. Diphenylmaleic anhydride is primarily used in the synthesis of various polymers and resins, particularly in the production of thermosetting plastics and as a curing agent in epoxy formulations. Its reactivity is attributed to the anhydride group, which can undergo hydrolysis, ring-opening reactions, and can participate in Diels-Alder reactions. Additionally, it exhibits good thermal stability and can enhance the mechanical properties of composite materials. Safety precautions should be taken when handling this compound, as it may cause irritation to the skin and eyes.
