Description and Uses

Diphenylphosphoryl azide (DPPA or diphenyl phosphorazidate, (PhO)2P(O)N3) is a very toxic and potentially explosive organic compound. DPPA has been found to be effective for a variety of organic reactions as a versatile synthetic reagent. It is widely used in synthesis of other organic compounds especially as a reagent for the synthesis of peptides by virtue of its reactions with carboxylic acids leading to either the urethane or the amide.
