Description

Diphenylphosphonic azide acts as a reagent for the synthesis of peptides and phosphoramidates by reacting with amines. It is also used in the preparation of oligosaccharides linked with carbamate and urea bonds utilizing modified Curtis rearrangement. It is involved in pseudohalogen replacement of the azido group by treatment with nucleophilic reagents, such as water, butanol, ammonia, and various amines. Further, it is used as a hydroazidation catalyst for preparation of organoazides.

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.
