Ethyl lactate is also used as solvent for nitrocellulose, cellulose acetate, and cellulose ethers. Ethyl lactate hydrolyzes in the presence of water and acids or bases into lactic acid and ethanol. Ethyl lactate can be used as a cosolvent to produce suitable conditions for the formation of aryl aldimines. Ethyl lactate Ethyl lactate, also known as lactic acid ethyl ester, is a monobasic ester formed from lactic acid and ethanol, commonly used as a solvent. This compound is considered biodegradable and can be used as a water-rinsible degreaser. Ethyl lactate is found naturally in small quantities in a wide variety of foods
Ethyl cyanohydroxyiminoacetate to HOAt without presenting an explosion risk such as the benzotriazoles. With water-soluble derivatives of ethyl cyanohydroxyiminoacetate (glyceroacetonide-oxyma) as additive and DIC as coupling reagent even in weakly basic aqueous solutions the linking of protected amino acids to oligopeptides is possible with a yield of 95% and a diastereomeric excess of> 99% using the model substances Z-"L"-Phg-OH and "L"-H-Pro-NH. In the coupling of amino acids, frequently occurring secondary reactions largely suppressed, which would be the formation of symmetrical acid anhydrides, racemization and epimerization and the cyclization to oxazolinones or - especially for dipeptides - to 2,5-diketopiperazines.
