  • Applications

    Diallyl Disulfide (CAS 2179-57-9) is primarily used as an odorant with a garlic-like aroma and may be employed as a fragrance note and, in some formulations, as a garlic-flavor note in specialty food applications; it also serves as an organic synthesis intermediate, leveraging its two allyl groups for further transformations. In polymer and coating contexts, it is explored as a potential crosslinking or reactive-building block for sulfur-containing materials. Within cosmetics/personal care and household products, it may be used as a fragrance ingredient under regulatory controls. In industrial manufacturing and research settings, it functions as a reagent for preparing sulfur-containing intermediates and as a subject of study for disulfide chemistry.
