Description

Application

N,N′-Disuccinimidyl carbonate (DSC) can be used to synthesize:

• Various carbamate derivatives from primary and sterically hindered secondary alcohols by alkoxycarbonylation.
• Active carbonate resins from 4-hydroxymethylpolystyrene and 4-hydroxymethyl-3-nitrobenzamido resins via hydroxy functional groups.
• Aza-glycinyl dipeptides, important intermediates for the preparation of various azapeptides.

It may be also used:

• In the two-step preparation of 5-(6-(azidomethyl)nicotinamido)pentanoic acid, a copper-chelating picolyl azide derivative.
• To activate the hydroxyl group of the hapten, γ-hydroxyphenylbutazone (HPBZ) so that HPBZ can effectively bind with human serum albumin(HSA)-immunogen to form a hapten-protein conjugate.

Other Notes

Convenient reagent for preparing N-succinimidyl esters of N-protected amino acids and other acids; activated carbonate, e.g. synthesis of ureas and carbamates; coupling of ligands to proteins (via lysines).
