Ethyl L(-)-lactate Usage And Synthesis
Chemical Propertiesclear liquid
UsesEthyl L-lactate is used in the preparation of food additives, aryl aldimines, fragrances and in pharmaceutical preparations. It can be considered as a green solvent in chemical industries due to its biodegradable nature. As a solvent, it used in the production of nitrocellulose, cellulose acetate and cellulose ethers.
Uses(-)-Ethyl L-Lactate is a naturally occuring chemical compound that is often used as an industrial solvent in chemical reactions.
DefinitionChEBI: The (2S)-enantiomer of ethyl lactate.
General DescriptionEthyl?lactate is an economically viable?green solvent used in organic synthesis. It is generally employed in organic reactions like multi-component reactions, cycloaddition reaction, asymmetric induction, photochemical synthesis, and ligand-free coupling reactions, etc.
