General description

Phosgene is an organic chemical compound widely used as a chlorinating agent, carbonylating agent, and dehydrating agent in organic synthesis for the synthesis of various compounds.

Application

Phosgene solution (~20% in toluene) can be used as a reagent in the synthesis of multiblock copolymers via multiple coupling reactions. It is also used in the activation of the hydroxyl groups in poly(ethylene glycol) diol (PEG diol) to synthesize linear multifunctional poly(ethylene glycol).

Phosgene gas is a lower respiratory tract irritant. As such, it stimulates nociceptive vagal C-fiber-related reflexes in a dose-rate and concentration × exposure duration (C × t)-dependent manner. In rats, this reflex is characterized by extended apnea time periods, bradycardia

The use of phosgene as a derivatizing agent for bifunctional compounds prior to gas and liquid chromatographic analysis is reviewed. Applications include gas chromatographic determinations of metoprolol and its metabolites in biological fluids, enantiomeric separations of beta-blocking drugs and sympathomimetic
