Product Description:

Ethyl levulinate is an organic compound with the formula CH3C(O)CH2CH2C(O)OCH2CH3. It is the ethyl ester of levulinic acid, characterized by a ketone and an ester functional group. It is a colorless to pale yellow liquid with a fruity, caramel-like odor. Its primary industrial application is as a flavor and fragrance ingredient. The fruity, sweet, and slightly caramelic aroma profile makes it valuable in the formulation of food flavorings, beverages, and perfumes. Beyond its organoleptic uses, ethyl levulinate serves as a versatile chemical intermediate and a promising bio-based platform chemical. It is used in the synthesis of various compounds, including pharmaceuticals, plasticizers, and fuel additives. Notably, it is considered a potential green solvent and a precursor for biofuels like ethyl valerate. As a derivative of levulinic acid, which can be produced from biomass, ethyl levulinate is of significant interest in green chemistry and sustainable industrial processes. It is also investigated for applications as a plasticizer and a low-toxicity solvent.
