Description

Methyl Allyl Trisulfide is an organosulfur compound characterized by its distinct chemical structure and potent organoleptic properties. This compound is significant for its role as a key flavor and aroma constituent, particularly in processed foods and flavor formulations where a robust, savory character is desired. It is primarily sought by manufacturers in the flavor and fragrance, food processing, and synthetic chemistry industries for applications requiring authentic savory or alliaceous notes.

Application

• Flavor & Fragrance Industry: A critical component for creating authentic garlic, onion, and savory flavor profiles in seasonings, sauces, snack foods, and processed meats.
• Food Processing: Used as a flavor enhancer and replacer in products where the use of fresh alliums is impractical, ensuring consistent taste and extended shelf life.
• Synthetic Intermediate: Serves as a valuable building block in organic synthesis for the preparation of more complex sulfur-containing molecules in pharmaceutical and agrochemical research.
• Aroma Chemicals: Employed in the formulation of specialty fragrances and aroma compounds that require sulfurous, pungent top notes.
• Research & Development: Used as a reference standard or active component in studies related to food chemistry, sensory science, and bioactive sulfur compounds.

Quality Control

Our Methyl Allyl Trisulfide is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and composition, aligning with industry expectations for flavor ingredients. Certificates of Analysis (COA) documenting purity (typically by GC), specific gravity, refractive index, and organoleptic properties are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at controlled room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening and minimize headspace to preserve quality and prevent degradation. Keep away from heat, sparks, and open flame.
