D-Tartaric acid Usage And Synthesis
| Chemical properties | There are three stereoisomers of tartaric acid: dextrose tartaric acid, levophyllic acid and meso tartaric acid. The optical rotation of the mixture of the same amount of dextrorotatory and levorotism is mutually offset, known as racemic tartaric acid. The mesomer does not exist in nature and can be synthesized chemically. Various tartaric acids are colorless crystals that are easily soluble in water. |
| Uses |
D-(-)-Tartaric Acid the synthetic enantiomer of L-(+)-Tartaric Acid, used in the preparation of synthetic analgesics. tartaric acid is the second largest AHA in size (glycolic acid being the smallest AHA and citric acid the largest). It is not frequently used in cosmetic or anti-aging preparations as formulators find it difficult to work with and it can cause irritation to the skin. D-(-)-Tartaric acid is used as a resolving agent in organic synthesis. It is used as a precursor for the preparation of its ester derivatives like D-tartaric acid diethyl ester, D-tartaric acid dimethyl ester and D-tartaric acid diiso-propyl ester. It finds application in the synthesis of chiral aziridine derivative, a common intermediate for the preparation of hydroxyethylamine class HIV protease inhibitors viz. as saquinavir, amprenavir and nelfinavir. It is widely used in the food industry as a beer foaming agent, for food acidity regulations and as a flavoring agent. |
