Appearance: Colorless to pale yellow liquid； Assay:99%min by GC； IR Identity: conform to standard； HNMR： conform to standard； carbon spectrum: conform to standard； Water by K. F.:0.5% max or as per the customer’s request； Loss on drying:0.5% max. or as per the customer’s request； =============================================================================== Purpose: Primarily used as a food flavor enhancer for food seasonings, it has been evaluated by the Joint FAO/WHO Expert Committee on Food Additives for use in food. In the flavor and fragrance industry, it is classified as a thioether-type fragrance. As a main food flavor enhancer, it imparts alliaceous (onion and garlic-like) aromas to food. It is applied to processed foods such as meat products, seasonings, soups, and snacks to enhance flavor complexity. Classified as a thioether-type fragrance in the flavor and fragrance industry, it has a low odor threshold, and only trace amounts are needed to significantly improve aroma complexity. =============================================================================== The synthesis route of ethyl 3-thiophenylpropionate is as follows: Raw Material Preparation: Furfuryl mercaptan (2-furanmethanethiol), ethyl bromopropionate (or ethyl chloropropionate) Nucleophilic Substitution Reaction: Under basic conditions (such as potassium carbonate or sodium hydroxide), the sulfur atom of furfuryl mercaptan undergoes an Sₙ2 nucleophilic substitution with ethyl bromopropionate, generating the target product: Purification: The product is purified by vacuum distillation or column chromatography to obtain a high-purity product (typically ≥98%). This reaction should be carried out under an inert atmosphere (such as nitrogen) and at low temperatures to avoid side reactions (such as oxidation or polymerization). (For reference only) Uses : It is primarily used as a food flavor enhancer and has been evaluated by the Joint Expert Committee on Food Additives for use in food. In the flavor and fragrance industry, it is classified as a sulfide-type fragrance.
