General description

Phosgene is used as a reagent in organic synthesis for various reactions such as carbonylation reaction and synthesis of isocyanates. Phosgene is formed during the free radical induced degradation of chlorinated hydrocarbons. Determination of phosgene in air samples using thermal desorption (TD) followed by gas chromatography-mass spectrometry (GC-MS) has been reported.

Application

Phosgene solution (15 wt. % in toluene) has been used to synthesize the following peptide monomers:
  • γ-(4-propargyloxybenzyl)-L-glutamic acid N-carboxyanhydride (POB-L-Glu-NCA)
  • γ-(4,5-dimethoxy-2-nitrobenzyl)-L-glutamate N-carboxyanhydride (DMNB-L-Glu-NCA)
  • γ-(4,5-dimethoxy-2-nitrobenzyl)-D-glutamate N-carboxyanhydride (DMNB-D-Glu-NCA)
  • 2-nitrobenzyl(4-vinylphenyl)carbamate

Phosgene solution may be used in the synthesis of:
  • sulfonyl chlorides
  • Fmoc (Fluorenylmethyloxycarbonyl chloride)-taurylsulfonyl chloride
  • O-benzyl-L-serine carboxyanhydrides

Packaging

The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.

O-benzyl-L-serine carboxyanhydrides were synthesized via diazotization of O-benzyl-L-serine with sodium nitrite in aqueous sulfuric acid solution followed by cyclization of the resulting serine-based α-hydroxy acid with phosgene. Degradable, water-soluble poly(α-hydroxy acids) bearing pendant hydroxyl groups were readily prepared under mild
