D-lactic acid with high optical purity

D-lactic acid with high optical purity (97%) as a chiral center is a variety of Ethyl lactate substance precursor, is an important intermediate of organic synthesis, chiral raw material, widely used in pharmaceutical, efficiency and low toxicity pesticides and herbicides , cosmetics and other fields chiral synthesis. The use of D-lactic acid manufacturing quality herbicides Puma (Puma Super). The D-lactic acid zinc lactate ester as raw herbicide Duplosan, and has mass market. In addition, calcium antagonists antihypertensive drugs, picolinic acid derivatives and MCPA acid, fluorine-based herbicides, also with high optical purity D-lactic acid as a raw material.
