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).
