  • Applications

    Diethyl tetrasulfide (CAS 13730-34-2) is typically used as an intermediate in organosulfur synthesis and as a sulfur-containing odorant note in fragrance research. In industry, it may serve as a sulfur donor or crosslinking reagent in polymer and rubber formulations, potentially aiding vulcanization or polysulfide chemistry. It can also be employed in coatings and inks as a trace additive or precursor in sulfur-containing resin systems. In laboratory settings, it is used as a reagent for preparing sulfur-rich intermediates and for exploratory sulfur-chemistry studies. The use of this compound is subject to local regulations and formulation limits.
