What is S-methyl Lactate？

L-methyl lactate, a transparent colorless liquid, also known as 2-hydroxypropionate methyl ester, α-hydroxyethyl propionate, etc., its physical properties are as follows: density 1.7±0.1g/cm3, boiling point 360.4±32.0° Cat760mmHg, vapor pressure 0.0±0.8mmHgat25°C, refractive index 1.638. Chemical properties: L-methyl lactate is soluble in water, but is easily decomposed by water. When the compound containing water is distilled under normal pressure, in addition to a considerable part of it being hydrolyzed to form lactic acid and methanol, some of it is polymerized. The hydrolysis rate is twice as fast as that of ethyl lactate.
