Succinic Anhydride is an organic compound with the molecular formula C₄H₄O₃. It is the cyclic anhydride of succinic acid and contains a five-membered ring with two carbonyl groups. It occurs as a white crystalline solid and has the reactive properties typical of acid anhydrides, allowing it to react with amine and hydroxyl groups. Succinic Anhydride is mainly synthesized industrially through the catalytic hydrogenation of maleic anhydride or by heating succinic acid at elevated temperatures to promote dehydration. It is widely used as a chemical intermediate in the preparation of polyester resins, functionalized surfaces, pharmaceuticals, cosmetics, and coatings.

Succinic anhydride is primarily used as a chemical intermediate in the manufacture of polymers, polyester resins, pharmaceuticals, agrochemicals, dyes, coatings and surface-active agents. It is also used as an epoxy curing and cross-linking agent.
Succinic anhydride is the cyclic acid anhydride of succinic acid. It can be produced by removing water from succinic acid through a dehydration process.
In laboratory preparation, succinic acid can be dehydrated thermally or with suitable dehydrating reagents. Industrially, succinic anhydride is commonly manufactured through the catalytic hydrogenation of maleic anhydride.
