Product Description:

4-Fluorobenzenethiol, also known as p-fluorothiophenol, is an organosulfur compound with the molecular formula C6H5FS. It is a colorless to pale yellow liquid with a characteristic unpleasant odor. It is a versatile building block in organic synthesis, featuring both a reactive thiol (-SH) group and a fluorine substituent on the aromatic ring. Its primary application is as a key intermediate in the synthesis of various pharmaceuticals and agrochemicals. The thiol group allows for the formation of thioethers (sulfides) and disulfides, while the fluorine atom can influence the electronic properties and metabolic stability of the final molecules. It is commonly used in nucleophilic aromatic substitution reactions and in the preparation of ligands for catalysis. It also serves as a precursor for materials such as liquid crystals. This compound requires careful handling due to its toxicity, potential for causing skin and eye irritation, and its malodorous nature. It should be stored under an inert atmosphere and used in a well-ventilated fume hood.
