Polymer materials and polymer industry

Crosslinking agents and modifiers: used in the synthesis of polyurethane, epoxy resins, through the participation of sulfhydryl groups in the reaction to improve the

flexibility of the material or heat resistance rubber processing.As vulcanization accelerator, enhance the elasticity and durability of rubber.

Surface treatment and metal protection

Metal corrosion inhibitors: sulfhydryl groups form stable complexes with metal ions (e.g. copper, silver) and are used in electroplating solutions or metal surface treatment

to prevent oxidation.

Self-assembled single molecule membranes (SAMs): form ordered film layers on the surface of gold, silver, etc., used in sensors or nanotechnology.

Pharmaceutical & Biotechnology

Cross-protein modification: sulfhydryl groups can react with disulfide bonds or amino groups of proteins for drug coupling (e.g., antibody-drug couplers, ADCs) or biomarkers.

Antioxidants: as free radical scavengers, with potential use in cosmetics or pharmaceutical formulations (subject to rigorous safety assessment).

Chemical synthesis and catalysts

Intermediates for organic synthesis: used in the synthesis of pharmaceuticals, pesticides (e.g. insecticides) or other sulfur-containing compounds.

Ligand or catalyst: used as a ligand in transition metal catalyzed reactions to modulate the reaction activity.
