Applications
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.

Solubility
Immiscible with water.

Notes
Store in a cool place. Incompatible with acids and oxidizing agents.
