Used as a stabilizing agent in the production of polymers, particularly in the synthesis of polyurethane and polyacrylate resins. It acts as a chain transfer agent, controlling molecular weight and improving the final product's properties. Applied in the pharmaceutical industry as a precursor for synthesizing various drugs, including those used in treating cardiovascular diseases and cancer. Its thiol group plays a key role in forming disulfide bonds, essential for drug stability and activity. Widely utilized in the cosmetics industry for its ability to modify hair proteins, making it a key ingredient in hair straightening and permanent wave products. It helps break and reform disulfide bonds in keratin, altering hair structure. In agriculture, it serves as an intermediate in the production of herbicides and fungicides, contributing to crop protection and yield improvement. Also employed in the manufacturing of adhesives and coatings, where it enhances adhesion and durability by acting as a cross-linking agent. Used in biochemical research as a reducing agent to maintain the stability of proteins and enzymes by preventing oxidation of thiol groups. Its versatility makes it valuable across multiple industries, from industrial manufacturing to healthcare and personal care.
