Description

Applications
Benzyl carbazate is used as a reagent for preparation of benzyloxycarbonyl (Z, Cbz) hydrazides of carboxylic acids, particularly N-protected amino acids. Subsequent hydrogenolysis gives the hydrazide which can be converted to the azide for coupling with a further amino acid residue by the azide method. It is also used in the preparation of simple acyl or sulfonyl hydrazides avoiding diacylation.

Solubility
Soluble in water (slightly), methanol and DMSO.

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Handle under inert gas. Protect from moisture. Incompatible with strong oxidizing agents.
