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.
Application
4-(Methylmercapto)phenol [4-(Methylthio)phenol] may be used in the preparation of phosphoramidodithioate intermediates for the synthesis of sulprofos amidate.
Storage Class Code

A novel ion/molecule reaction was observed to occur under electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photo ionization (APPI) conditions, leading to dimerization of ionized 4-(methyl mercapto)-phenol followed by fast H(*) loss. The reaction is particularly

A highly efficient transition-metal-free catalytic system Br2/NaNO2/H2O has been developed for a robust and economic acid-free aerobic oxidation of sulfides. It is noteworthy that the sulfide function reacts under mild conditions without over-oxidation to sulfone. The role of NaNO2as an

Oxygen-limited cultures of Klebsiella pneumoniae reduced 4-methylsulfinyl phenol to 4-methylthiophenol. A study of the effect of 4-methylthiophenol on the growth of K. pneumoniae revealed that the specific growth rate was retarded by 40% in the presence of 200 micrograms of
