Description

2,4-Difluorobenzene-1-thiol (CAS No. 1996-44-7) is a high-purity fluorinated aromatic thiol compound with the molecular formula C₆H₄F₂S. This specialized chemical is characterized by its reactive thiol (-SH) group and two fluorine substituents at the 2 and 4 positions of the benzene ring, offering unique electronic and steric properties for advanced synthetic applications. It is supplied as a clear to pale-yellow liquid with a distinctive odor, and is rigorously tested for purity (typically ??97% by GC) to ensure consistency in research and industrial processes. Ideal for use in pharmaceuticals, agrochemicals, and materials science, this compound serves as a versatile building block for the synthesis of sulfur-containing heterocycles, ligands, and fluorinated polymers. Proper handling under inert atmospheres is recommended due to its air-sensitive nature.

Application

2,4-Difluorobenzene-1-thiol is widely employed as a key intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals, where its thiol group facilitates nucleophilic substitution reactions. It is also utilized in materials science for modifying surfaces or creating sulfur-containing polymers with enhanced thermal and chemical resistance. Researchers leverage its fluorinated aromatic structure in catalysis and ligand design for transition metal complexes.
