Used as a crosslinking agent in polymer chemistry, particularly in the development of self-healing materials and responsive hydrogels. Its disulfide bond allows for reversible bond formation under mild conditions, making it ideal for dynamic networks that can repair damage or adapt to environmental changes. Also utilized in cosmetic formulations as a mild oxidizing agent for hair restructuring, providing improved strength and texture without harsh chemical exposure. Additionally, serves as a building block in synthesizing biocompatible polymers for drug delivery systems due to its biodegradable and redox-sensitive characteristics.
