Description and Uses

Succinimide is a natural product found in Xanthium strumarium and Panax notoginseng with data available.Succinimide is a colorless acicular crystal or thin solid with light brown luster. It tastes sweet. Easily soluble in water, alcohol or sodium hydroxide solution, insoluble in ether, chloroform, etc.
Succinimide dispersants appear as dark or brown-colored liquids with a thickness or viscosity similar to heavy syrup. They have little or no solubility in water, and because they are denser than water, will sink in a water environment. They are readily soluble in oil and lighter weight hydrocarbons, such as gasoline. Succinimide dispersants have very low vapor pressure and little noticeable odor at ambient temperatures.

Succinimide is a cycle imide of succinic acid that is present in numerous biologically active compounds including anticonvulsants, antitremor, anti-Parkinson's agents.
Succinimide is the key intermediate for deamidation of asparagine (Asn) and isom-erization of aspartic acid (Asp) residues in a protein or peptide, either in vivo or invitro (Wakankar and Borchardt 2006). Formation of succinimide is the rate-deter-mining step in these reactions.
