Common NameBenzenethiol
DescriptionBenzenethiol, also known as mercaptobenzene or phenyl mercaptan, belongs to the class of organic compounds known as thiophenols. Thiophenols are compounds containing a thiophenol ring, which a phenol derivative obtained by replacing the oxygen atom from the hydroxyl group (attached to the benzene) by a sulfur atom. Benzenethiol is a very weakly acidic compound (based on its pKa). Benzenethiol is a garlic, penetrating, and repulsive tasting compound. Outside of the human body,. Benzenethiol is a flavouring agent Benzenethiol is a chemical compound with the formula C6H5SH, and sometimes abbreviated as PhSH. The prefix thio- implies a sulfur-containing compound and when used before a root word name for a compound which would normally contain an oxygen atom, thio- commonly means that the oxygen atom is replaced by a sulfur atom. Benzenethiol was first documented in 2008 (PMID: 18266323). The organosulfur ligand in medicine merthiolate is a thiophenol (PMID: 23902004) (PMID: 23961762) (PMID: 18321603) (PMID: 22121689).
