Application

m-Bromobenzenethiol serves as a key intermediate in the synthesis of sulfur-containing heterocycles and ligands for transition metal catalysts. It is employed in palladium-catalyzed cross-coupling reactions (e.g., thioetherification) to construct complex aryl sulfides. The compound also finds use in surface modification of nanomaterials and as a chain transfer agent in polymer chemistry. Researchers utilize its reactive thiol group for bioconjugation and self-assembled monolayer (SAM) formation on gold surfaces.
