Succinimide is a cyclic imide

Imide

In organic chemistry, an imide is a functional group consisting of two carbonyl groups bound to nitrogen. These compounds are structurally related to acid anhydrides. The relationship between esters and amides and between imides and anhydrides is analogous, the amine-derived groups are less reactive...

 with the formula C₄H₅NO₂. It is used in a variety of organic syntheses, as well as in some industrial silver plating processes.

Succinimides

Succinimides refers to compounds that contain the succinimide group. These compounds have some notable uses. Several succinimides are used as anticonvulsant

Anticonvulsant

The anticonvulsants are a diverse group of pharmaceuticals used in the treatment of epileptic seizures. Anticonvulsants are also increasingly being used in the treatment of bipolar disorder, since many seem to act as mood stabilizers, and in the treatment of neuropathic pain. The goal of an...

 drugs, including ethosuximide

Ethosuximide

Ethosuximide is a succinimide anticonvulsant, used mainly in absence seizures.-Approved:It is approved for absence seizures. Ethosuximide is considered the first choice drug for treating absence seizures in part because it lacks the idiosyncratic hepatotoxicity of the alternative anti-absence...

Phensuximide

Phensuximide is an anticonvulsant in the succinimide class.-Chemistry:Phensuximide, 1-methyl-3-phenylpyrrolidine-2,5-dione is synthesized by the reaction of phenylsuccinic acid or its anhydride with methylamine.*C.A. Miller, L.M. Long, ....

, and methsuximide. Succinimides are also used to form covalent bonds between proteins or peptides and plastics, which is useful in a variety of assay

Assay

An assay is a procedure in molecular biology for testing or measuring the activity of a drug or biochemical in an organism or organic sample. A quantitative assay may also measure the amount of a substance in a sample. Bioassays and immunoassays are among the many varieties of specialized...
