  What is the chemical of 2-Ethyl-4-methylthiazole? Appearance: Color to light yellow transparent liquid. Odor: It has nutty aroma, happy fruit aroma, coffee aroma, meat aroma, and slight sulfur aroma, presenting pleasant aroma characteristics at low concentrations ; 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 ; boiling point: 161-162 ° C (atmospheric pressure, lit.); ============================================================================== main purpose Food essence: It is widely used to prepare food essence, giving coffee, sesame, meat products, nuts, cheese and other foods a unique aroma. It is a food flavor (FEMA No.: 3680, JECFA No.: 1044). Industrial application: As an organic synthesis intermediate, it is used for large-scale production of essence and fragrance industry. Others: It can be used as a fixative at very low concentrations to enhance the durability of essence. =============================================================================== synthetic route The typical synthesis method of 2-ethyl-4-methylthiazole is as follows: Raw material reaction: Propionamide reacts with phosphorus pentoxide (P ? O ?) to produce the intermediate of thionamide. Cyclic condensation: Thioketamide undergoes a condensation reaction with chloroacetone to form a thiazole ring structure, ultimately yielding the target product. This method is a classic synthetic pathway commonly used in industry, with mild reaction conditions and high yields
