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 principal acute mode of action of inhaled phosgene gas is related to an increase alveolar fluid exudation under pathologic conditions. This paper considers some aspects in modeling phosgene-induced acute lung injury (ALI) in an acute rat bioassay and whether

Phosgene is a poorly water-soluble gas penetrating the lower respiratory tract which can induce acute lung injury characterized by a latent phase of fatal pulmonary edema. Pulmonary edema caused by phosgene is believed to be a consequence of oxidative stress
