Allyl Methyl Sulfide CAS 10152-76-8 | FEMA 3125 | Food & Perfume Ingredient

Allyl Methyl Sulfide, accurately identified by its CAS registry number 10152-76-8 and commonly known under synonyms such as Methyl allyl sulfide and 3-(Methylthio)-1-propene, is an important organosulfur compound widely utilized in the flavor and fragrance industry. Its safety and suitability for use in consumable products are formally recognized through its FEMA number 3125, classifying it as an approved flavoring substance. This clear to pale yellow liquid possesses a characteristic pungent aroma strongly associated with fresh garlic and other allium species, making it a fundamental ingredient for developing authentic savory flavor and aroma profiles.

In the food and beverage industry, Allyl Methyl Sulfide serves as an essential flavoring agent and flavor enhancer. It is extensively employed in the formulation of food flavorings designed to replicate or intensify the savory, pungent notes characteristic of garlic, onion, and related allium vegetables. This compound is a key component in flavor systems for processed foods including savory snacks, ready-to-eat meals, sauces, soups, salad dressings, marinades, and both meat-based and plant-based protein products. Its distinct aromatic profile allows flavorists to create realistic and robust flavor experiences at controlled usage levels, enhancing the overall sensory appeal of food products.

Within the fragrance and personal care industry, Allyl Methyl Sulfide functions as a valuable aroma chemical and fragrance ingredient. Perfumers and scent designers utilize its sharp, sulfurous, and vegetable-like olfactory characteristics to introduce fresh, green, and savory nuances into various scent compositions. It is applied in fine fragrances, personal care products, and household items, where it contributes to creating complex, natural, or distinctive olfactory signatures.

From a technical perspective, this compound also acts as a useful chemical intermediate in organic synthesis. Research and development laboratories may employ it as a building block for synthesizing more advanced sulfur-containing molecules, which can have applications in material science or in the development of novel aroma compounds. Its FEMA GRAS (Generally Recognized As Safe) status, associated with FEMA 3125, is essential for its compliant use in food-grade applications globally. Manufacturers and flavor houses sourcing this material typically require high-purity Allyl Methyl Sulfide from reliable suppliers capable of providing consistent quality, detailed technical specifications, comprehensive safety data sheets (SDS), and necessary regulatory documentation to ensure its safe and effective integration into final products.
