  • Applications

    Allyl disulfide, also known as diallyl disulfide, is the principal aroma compound of garlic and is widely used to formulate savory flavors for sauces, snacks and processed meat, to build thermally stable onion-garlic notes in fragrance compositions; in nutraceuticals and pharmaceuticals it is investigated as an antioxidant, antimicrobial, cholesterol-lowering and hepatoprotective agent; in agriculture it functions as an insect repellent, antifungal additive and germination promoter; in organic synthesis it serves as a versatile sulfur donor for polysulfide production, rubber vulcanization, polymer modification, and as a precursor to thiols, sulfoxides and sulfones; laboratories employ it as a calibration odorant for analytical instruments, a surface-grafting reagent on metals, a sulfur-isotope tracer for mechanistic studies, and as a model compound to explore the bioactivity of natural organosulfur molecules.
