1-Thioglycerol is widely used in biochemical research as a reducing agent to maintain the stability of proteins and enzymes by preventing oxidation. It is particularly valuable in electrophoresis and chromatography techniques, where it helps in preserving the native structure of biomolecules. Additionally, it is employed in the preparation of culture media for cell and tissue growth, ensuring optimal conditions for biological studies. In the cosmetic industry, it serves as a key ingredient in hair care products, aiding in the permanent waving of hair by breaking and reforming disulfide bonds in keratin. Its applications also extend to pharmaceutical formulations, where it acts as an antioxidant and stabilizer in various drug preparations.
