  • Applications

    Decyl disulfide is an organic sulfur compound with a disulfide linkage (CAS 10496-18-1). In industry it is primarily used as an intermediate in organic synthesis to access longer-chain sulfur-containing derivatives; it is employed as a building block for surface functionalization and crosslinking in polymers, coatings, and adhesives; in elastomer and rubber formulations it may be evaluated as a sulfur source or crosslinking additive; in perfumery and fragrance applications it may serve as a fixative or odor component; and in research and development it is used as a precursor for higher-order disulfides and thio derivatives.
