Succinimide（Cat No.:R029599）is a white, crystalline organic compound with the formula C₄H₅NO₂, featuring a five-membered ring containing two carbonyl groups and a nitrogen atom. It is widely used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and other fine chemicals. In medicinal chemistry, derivatives of succinimide—such as ethosuximide—are employed as anticonvulsants to treat epilepsy. Succinimide also serves as a reagent in peptide synthesis and as a stabilizer in industrial formulations. Its cyclic imide structure contributes to its chemical reactivity and versatility in both laboratory and industrial applications.
