Allyl Propyl Disulfide CAS 2179-59-1 | FEMA 4073 | Flavoring & Fragrance Agent

Allyl Propyl Disulfide, precisely identified by its CAS registry number 2179-59-1, is an organosulfur compound of significant commercial importance in the flavor and fragrance industry. It is also commonly known under the synonym Prop-2-en-1-yl propyl disulfide and is recognized for its characteristic pungent, savory aroma reminiscent of fresh onion and garlic. Its established safety profile for use in consumable products is validated through its FEMA (Flavor and Extract Manufacturers Association) number 4073, classifying it as an approved flavoring substance. This clear to pale yellow liquid serves as a key building block for creating authentic allium flavor profiles.

As a highly effective flavoring agent, Allyl Propyl Disulfide is extensively utilized in the food industry to replicate and enhance the savory, pungent notes of onion, garlic, and other allium species. It is a critical component in the formulation of food flavorings for a wide range of products, including savory snacks, processed meats, sauces, dressings, soups, ready-to-eat meals, and condiments. Flavorists value its ability to impart a robust and authentic flavor profile at controlled concentrations, making it indispensable for creating complex savory taste experiences. In the fragrance industry, this compound is employed as a valuable aroma chemical and fragrance ingredient. Its distinctive sulfurous and fresh character is used by perfumers to introduce sharp, green, or vegetable-like nuances into fragrance compositions for personal care products, fine perfumes, and household items, adding a unique layer of olfactory depth.

From a technical perspective, Allyl Propyl Disulfide also functions as a useful chemical intermediate in organic synthesis. Research and development laboratories may utilize it as a building block for the preparation of more complex sulfur-containing molecules, potentially for applications in material science or the synthesis of other specialized aroma compounds. Its FEMA GRAS status, associated with FEMA 4073, is essential for its compliant use in food-grade applications globally. Manufacturers and flavor houses sourcing this material typically require high-purity Allyl Propyl Disulfide from reliable suppliers who can provide detailed technical specifications, comprehensive safety data sheets (SDS), and regulatory documentation to ensure quality and suitability for intended applications.
