D-(-)-Tartaric acid 147-71-7 Usage
D-(-)-Tartaric acid is a polycrystalline solid, widely used as an acidizing agent for beverages and other foods, and this use is similar to citric acid. Tartaric Acid is an acidulant that occurs naturally in grapes. It is hygroscopic and rapidly soluble, with a solubility of 150 g in 100 ml of distilled water at 25°c. D-tartaric acid is the D-enantiomer of tartaric acid. It has a role as an Escherichia coli metabolite. It is a conjugate acid of a D-tartrate(1-). 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. The difference between L tartaric acid and D-tartaric acid is that they have an OH group on the right hand side in d- configuration, while on the left hand side in l- configuration.
