Succinic anhydride is a cyclic anhydride of succinic acid with a five-membered ring. It is widely used in the manufacture of polymeric materials, pharmaceuticals, agrochemicals, dyes, surface-active agents, and organic flame-retardant materials. It also finds application as a cross-linking agent in ion-exchange membranes and a curing agent for epoxy resins.
