Used as an intermediate in organic synthesis, particularly in the preparation of sulfide and disulfide compounds. It serves in the development of pharmaceuticals and agrochemicals due to the presence of the bromoaryl and thioate functional groups, which allow for cross-coupling reactions and nucleophilic substitutions. Commonly employed in research settings to introduce the 4-bromophenylthio moiety into target molecules, aiding in the modification of biological activity or physicochemical properties. Also utilized in the synthesis of ligands for catalysis and in the formation of thiophenol derivatives through reduction or hydrolysis.
