Succinic acid is a diprotic, dicarboxylic acid with chemical formula C4H6O4 and structural formula HOOC-(CH2)2-COOH. It is a white, odorless solid. Succinate plays a role in the citric acid cycle, an energy-yielding process. The name derives from Latin succinum, meaning amber, from which the acid may be obtained
Industrially, succinic acid is often prepared by catalytic reduction of butenedioic acid, and succinic acid can also be prepared by hydrolysis of succinonitrile. In the laboratory, succinic acid can be prepared by reacting two molecules of sodium diethyl malonate with iodine, followed by hydrolysis and decarboxylation.
An important use of succinic acid is to prepare five-membered heterocyclic compounds. For example, succinic acid loses water rapidly when heated to form succinic anhydride, which is a ring compound. Succinic anhydride is an important raw material for manufacturing drugs, dyes and alkyd resins. Succinic anhydride are heated together to generate succinimide. The hydrogen on the imine group of succinimide can be replaced by to produce N-bromosuccinimide, which is a bromination reagent and mild oxidant for organic synthesis. Succinic acid has antispasmodic, expectorant and diuretic effects in medicine. Diethyl succinate is an important intermediate in organic synthesis. Dibutyl succinate and dioctyl succinate are plasticizers for plastics. Copolymerization of diallyl succinate can produce artificial rubber.
