Thiophenol (PhSH) is an organosulfur compound with the chemical formula C6H5SH. This colourless liquid, characterized by a foul smell, is the simplest aromatic thiol. The structural resemblance of thiophenol and its derivatives to phenols lies in substituting the oxygen atom in the hydroxyl group (-OH) with a sulfur atom. The prefix "thio-" indicates the presence of sulfur in the compound. In the case of thiols, this implies the replacement of the alcohol oxygen atom with a sulfur atom, making them analogous to phenols with sulfur substitution.
