The Uses of 4-(Methylthio)phenol
4-(Methylmercapto)phenol [4-(Methylthio)phenol] may be used in the preparation of phosphoramidodithioate intermediates for the synthesis of sulprofos amidate.
Definition
ChEBI: 4-(methylsulfanyl)phenol is an aryl sulfide and a member of phenols.
General Description
4-(Methylmercapto)phenol (4MP) mediates the removal of benzyloxycarbonyl and O-benzyl protecting groups by accepting the benzyl groups during the acidolytic cleavage with trifluoroacetic acid. The presence of hydroxyl group in the para position enhances the rate of hydrodesulfurization (HDS) of 4MP.
