4-Fluorothiophenol (Cat No.: R045707) is an organosulfur compound featuring a fluorine atom para to a thiol group on a benzene ring. It appears as a pale yellow liquid with a strong, unpleasant odor and is used primarily as a building block in organic synthesis. The thiol group allows for nucleophilic substitution and thiol-ene click reactions, while the fluorine imparts electronic modulation and metabolic stability. It is employed in the development of pharmaceuticals, agrochemicals, and advanced materials. Proper handling is essential due to its volatility and odor.
