说明

General description

乳酸乙酯是用于有机合成的绿色环保溶剂。它通常用于多组分反应、环加成反应、不对称诱导、光化学合成和无配体偶联反应等有机反应。

Application

(−)-L-乳酸乙酯可用于制备：

(R)-(+)-2-甲基环氧乙烷。
(S)-2-((叔丁基二甲基硅基)氧基)丙醛，一种用于合成maltepolide的关键中间体。

Features and Benefits

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is a safer and more sustainable alternative to ethyl acetate and acetone. It is an ester of natural L-lactic acid, which is produced by fermentation of sugar and thus aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks".
