General description

Diethyl cyanophosphonate (DCNP, a Tabun mimic,[1] DECP[2]) is a nerve agent simulant. Its detection by using fluorescein, a reversible fluorescent sensor, has been reported.[2] Its degradation in the presence of suitable organocatalysts (different amines, aminoalcohols and glycols) has been studied.[1]

Application

Coupling reagent for peptide synthesis.[3] Reagent for the phosphorylation of phenols.[4] Activating agent for fluorescent derivatization of carboxylic acids which allows separation by HPLC.[5]
