2-(Phenylthio)ethanol

It combines a lipophilic aromatic moiety with a reactive primary hydroxyl group, giving it balanced polarity and good synthetic flexibility. The sulfur atom increases polarizability and can be readily oxidized to sulfoxide or sulfone, while the alcohol group allows esterification or further functionalization. Because of this dual reactivity, 2-(phenylthio)ethanol is widely applied as an intermediate in pharmaceutical, agrochemical, and fine-chemical synthesis, particularly where sulfur-containing side chains are required. 2-(Phenylthio)ethanol is an aromatic sulfur-containing alcohol composed of a phenyl ring linked through a thioether (–S–) to a two-carbon alcohol chain (–CH₂CH₂OH).
