Description and Uses
D-(-)-Tartaric acid is commonly used as a resolving agent in organic synthesis. It is the synthetic enantiomer of L-(+)-Tartaric acid and is utilized in the production of synthetic analgesics. Tartaric acid is the second largest alpha hydroxy acid (AHA) in terms of size, with glycolic acid being the smallest and citric acid being the largest. It serves as a precursor for the synthesis of ester derivatives such as D-tartaric acid diethyl ester, D-tartaric acid dimethyl ester, and D-tartaric acid diiso-propyl ester. Moreover, it is employed in the creation of chiral aziridine derivative, which is a common intermediate for manufacturing hydroxyethylamine class HIV protease inhibitors like saquinavir, amprenavir, and nelfinavir. In the food industry, it is extensively used as a beer foaming agent, for regulating food acidity, and as a flavoring agent. However, due to its challenging workability and potential skin irritation, it is not frequently utilized in cosmetic or anti-aging preparations.
