Benzyl carbazate, 98+%, Thermo Scientific Chemicals

Catalog No. AAA1300522
Click to view available options
Quantity:

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
