  • Applications

    Methyl 1-propenyl trisulfide (CAS 23838-25-7) is a volatile organosulfur compound with a characteristic onion/garlic odor, used primarily as a flavor ingredient at trace levels to build onion-, garlic-, and cooked Allium notes; as an analytical reference/calibration standard in GC-MS/GC-FID studies of volatile sulfur compounds in food matrices; as a reagent/precursor in organic synthesis to introduce trisulfide linkages, to access related di-/polysulfides, or to tune sulfur content in materials; investigated in pharmacological and microbiological research as a representative alkenyl trisulfide with antimicrobial, radical-scavenging, and odor-active properties; and, at research scale, as a functional additive in polymers/rubber and lubricants to enhance adhesion, extreme-pressure performance, and antiwear/corrosion behavior in specialized formulations; it also occurs in cooked onion/garlic samples and is useful for provenance studies, sensory evaluation, and quality control. Handle with care due to the intense odor and the reactivity of the –S–S–S– functionality, following appropriate chemical safety practices.
