Used as a key intermediate in the synthesis of sulfur-containing organic compounds, particularly in the production of vulcanization accelerators for rubber manufacturing. It plays an important role in improving the curing process of rubber, enhancing elasticity, durability, and heat resistance. Also utilized in the development of certain dyes and fluorescent whiteners due to its reactive sulfinate group. Its derivatives show potential in pharmaceutical applications, including as building blocks for bioactive molecules and antimicrobial agents. Additionally, it serves in some industrial formulations as a stabilizer or antioxidant.
