Details

SiliaBond® Carbamate (CAR) is a versatile scavenger for nucleophiles. It readily scavenges amines, thiols, thiolates, alcohols, alkoxides, and acidic phenols. Loading is determined by the removal of benzylamine in hexane at room temperature.

Si-CAR has been used to scavenge amines in a “cap-tag” methodology for oligosaccharide preparation by automated solid phase synthesis1 and in the preparation of 2,5-diketopiperazines and 1,4-benzodiazepine-2,5-diones.2

Silica supported Carbamate has superior reactivity in a broader range of solvents when compared to polymer-based materials.
