Description

3-(Methylthio)Hexyl Acetate is a sulfur-containing ester known for its distinctive, powerful aroma profile, often described as fruity, tropical, or reminiscent of passionfruit. This compound matters for formulators seeking to create complex, natural-smelling flavor and fragrance compositions with excellent stability and impact. It is primarily needed by manufacturers in the flavor and fragrance industry, as well as by research and development laboratories working on aroma chemicals and specialty intermediates.

Application

• Flavor & Fragrance Formulation: A key ingredient in creating tropical fruit flavors (e.g., passionfruit, grapefruit, mango) and enhancing fruity nuances in perfumes, cosmetics, and personal care products.
• Food & Beverage Industry: Used as a flavoring agent in beverages, confectionery, dairy products, and desserts to impart exotic fruit notes.
• Fine Fragrance & Perfumery: Serves as a middle to top note in perfume compositions, adding freshness and a unique sulfurous-fruity character to modern scents.
• Household & Industrial Products: Incorporated into air fresheners, detergents, and fabric softeners to provide a pleasant, fruity aroma.
• Chemical Synthesis: Acts as a valuable intermediate or building block in organic synthesis for pharmaceuticals and other specialty chemicals.
• Aroma Chemical Research: Utilized in R&D for studying structure-odor relationships and developing new aroma molecules.

Quality Control

Our 3-(Methylthio)Hexyl Acetate is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including GC, IR, and NMR. Certificates of Analysis (COA) detailing identity, purity, and specific impurity profiles are provided with every shipment. The product is manufactured in compliance with relevant industry guidelines for flavoring substances, including FEMA GRAS status (FEMA 3789).

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening to maintain optimal quality and prevent degradation. Keep away from heat, sparks, and open flames.
