Succinic anhydride is a cyclic organic anhydride derived from succinic acid, widely used as a chemical intermediate in pharmaceuticals, coatings, and plasticizers. It serves as a key reagent in organic synthesis, a curing agent for epoxy resins, and an acylating agent for introducing succinyl groups onto amines and alcohols, for example in the succinylation of proteins. Catalogue details: CAS 108-30-5, molecular formula C4H4O3, molecular weight 100.07 g/mol, stored at ambient conditions. Hazard classification includes a signal word of Danger due to corrosive properties. Molekula supplies Succinic anhydride from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
