Used as an intermediate in the synthesis of organic sulfur compounds, particularly in the production of rubber chemicals and vulcanization accelerators. It also finds application in the formulation of certain agrochemicals and pharmaceuticals where disulfide linkages are required. Due to its reactive thiol and hydroxyl groups, it can act as a building block in crosslinking agents or surface modifiers in polymer chemistry. Additionally, it may be employed in research for developing biologically active molecules involving redox-active disulfide bonds.
