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 a vulcanization accelerator, to enhance the elasticity and durability of rubber.
Surface treatment and metal protection
Metal corrosion inhibitor: mercapto group can form stable complex with metal ions (such as copper, silver), used in plating solution or metal surface treatment to prevent oxidation.
Self-assembled single molecule membranes (SAMs): form ordered film layers on the surface of gold, silver, etc. for sensors or nanotechnology.
Pharmaceuticals & 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 possible 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.
Ligands or catalysts: used as ligands in transition metal-catalyzed reactions to modulate reaction activity.
