General description

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

Application

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

Other Notes

Contains triethyl phosphate
