General description

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.

Application

Succinic anhydride can be used:
  • In the preparation of covalently cross-linked oxidized-alginate/N-succinyl-chitosan hydrogels, as injectable systems towards tissue engineering.
  • In preparing functionalized oxide surfaces on a chip.
  • As a starting material to synthesize polyesters in presence of a metal triflate as a catalyst.
  • As a cross-linking agent to enhance the mechanicalproperties and antimicrobial activities of zein films.

Chemotherapeutic drugs used for cancer therapy frequently encounter multiple-drug resistance (MDR). Nanoscale carriers that can target tumors to accumulate and release drugs intracellularly have the greatest potential for overcoming MDR.
