Description

3-(Methylthio)Propyl Butyrate is a sulfur-containing ester with a distinctive, powerful aroma profile. This compound matters as a versatile flavor and fragrance intermediate, prized for its ability to impart fruity, tropical, and savory notes. It is primarily needed by manufacturers in the flavor and fragrance industry, as well as by food technologists and perfumers seeking to create complex, natural-tasting profiles.

Application

• Flavor & Fragrance Industry: A key building block for creating complex fruity (e.g., pineapple, passionfruit), tropical, and savory flavor nuances in food, beverages, and confectionery.
• Perfumery: Used as a fragrance ingredient to add depth and unique sulfurous, fruity, or meaty character to fine fragrances and personal care products.
• Food Processing: Employed as a flavor enhancer in processed foods, savory snacks, and meat flavorings to replicate natural taste profiles.
• Aroma Chemical Synthesis: Serves as a valuable intermediate in the synthesis of more complex sulfur-containing aroma chemicals.
• Research & Development: Utilized in analytical and R&D laboratories as a reference standard and for studying structure-odor relationships.
