Applicazioni

Succinic anhydride is used as a sizing agent and curative for epoxy resin. It acts as an additive in paper production. It is utilized in the preparation of covalently cross-linked oxidized-alginate and N-succinyl-chitosan hydrogels. It serves as an intermediate for functionalized oxide surfaces on a chip and for polyester resins. Further, it finds use in cosmetics, pharmaceuticals and in coatings.

Note

Moisture sensitive. Incompatible with strong oxidizing agents, alcohols and amines.

Friedel-Crafts reaction with arenes gives 3-aroylpropionic acids: Org. Synth. Coll., 2, 81 (1943). For a review of the Friedel-Crafts reactions of the anhydrides of dibasic acids, see: Org. React., 5, 229 (1949).

For reaction with phosphoranes, in a route to 2,2-disubstituted cyclopentane-1,3-diones, see (1-Ethoxycarbonyl­ethyl­idene)­triphenyl­phosphorane, A15619.

A method for protecting both H atoms of a primary amine consists of formation of the succinimide, followed by enolsilylation with Triisopropyl­silyl­ trifluoromethanesulfonate, B21127, to form the 2,5-bis(triisopropylsiloxy)pyrroles. Deprotection can be effected by desilylation with dilute HCl, followed by hydrazinolysis: Tetrahedron Lett., 38, 2617 (1997). Peng, S.; Xue, L.; Leng, X.; Yang, R.; Zhang, G.; Hamaker, B. R.
