Lactic Acid Pharmaceutical Grade Lactic Acid 500g Skin Acid-Base Regulating Food Preservative Lactic Acid Pharmaceutical Grade Lactic Acid 500g Skin Acid-Base Regulating Food Preservative Alias DL-Lactic acid; 2-hydroxypropanoic acid; Acidum lacticum; Milk acid; racemic lactic acid; E270; Eco-lac Chemical name 2-hydroxypropionic acid; 2-hydroxypropionic acid CAS No.
50-21-5 2-hydroxypropionic acid , α-hydroxypropionic acid, there is an asymmetric carbon atom in the molecular structure, forming two optical isomers d-body, l-body and racemate dl-body, there are 3 kinds of optical isomers
.
Those obtained by fermentation or synthetic methods are all racemates
.
Due to the presence of hydroxyl and carboxyl groups in the molecule, this product has the functions of these two functional groups, forming carboxylate with acid anhydride, forming lactate with alcohol, and forming salt with sodium, calcium, ferrous ions and other ions; Hydroxyl and carboxyl groups, therefore, can undergo self-esterification to generate linear polyesters and even cyclic compounds, namely cyclic dimer lactide [2]
.
Oxidation under slow conditions, this product can generate pyruvic acid
