Appearance: Colorless transparent liquid with strong aromas of apple peel, pineapple peel, and immature plum peel ; 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 ; ====================================================================== According to GB 2760-96 and GB 2760-2014, it is allowed to be used as an edible spice. It is mainly used to prepare tropical fruit essence such as apple, strawberry, grape, raspberry, mango, etc. Applied to baked goods, frozen dairy products, pudding and other foods. Natural products are found in natural foods such as apples, wine, brandy, strawberries, melons, etc ============================================================================= The esterification reaction between 2-methylbutyric acid and ethanol: This is the most direct synthetic pathway, usually using 2-methylbutyric acid as the raw material, and esterification reaction with ethanol in the presence of acidic catalyst (such as concentrated sulfuric acid) to generate ethyl 2-methylbutyrate. Catalytic synthesis from ethylene and carbon monoxide: an industrial synthesis method involves reacting ethylene and carbon monoxide under pressure using tetrafluoroboric acid and hydrofluoric acid as catalysts. Synthesis by hydrogenation reaction: One laboratory method is to suspend olefins (such as 2-methyl-2-butene) with palladium carbon (Pd/C) catalyst in methanol for low-pressure hydrogenation reaction, followed by purification steps to obtain the product. Other synthetic routes: Various other synthetic routes have also been reported in the literature, such as oxidation and esterification using 2-methylbutanol as raw material, or reaction through different carboxylic acid derivatives, totaling over 30 known synthetic routes Uses : as apple, strawberry, grape, raspberry, mango, etc. Synonyms : Ethyl 2-methylbutanoate;2-Methylbutyric acid ethyl ester;D-ethyl 2-methylbutyrate;Ethyl 2-Methyl Butyrate;D-Ethyl 2-Methyl Butyrate;ethyl (2R)-2-methylbutanoate; Molecular Structure :
