General description: 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:. +¦-(4-propargyloxybenzyl)-L-glutamic acid N-carboxyanhydride (POB-L-Glu-NCA). +¦-(4,5-dimethoxy-2-nitrobenzyl)-L-glutamate N-carboxyanhydride (DMNB-L-Glu-NCA). +¦-(4,5-dimethoxy-2-nitrobenzyl)-D-glutamate N-carboxyanhydride (DMNB-D-Glu-NCA). 2-nitrobenzyl(4-vinylphenyl)carbamate
Application: Phosgene solution may be used in the synthesis of:. sulfonyl chlorides. Fmoc (Fluorenylmethyloxycarbonyl chloride)-taurylsulfonyl chloride. O-benzyl-L-serine carboxyanhydrides
