Popis

General description

D-(-)-Tartaric acid is a polycrystalline solid, widely used as food additive. It has been reported to exhibit piezoelectric effect.

D-(−)-Tartaric acid is a polyhydroxy acid. Oxidation of d-tartaric acid has been reported. Crystal structure of D-(−)-tartaric acid has been studied by X-ray and neutron diffraction. Tartaric acid is reported to be one of the constituents of soy bean Lipositol. Tartaric acid assists in the generation Y₂O₃:Eu³⁺ nanoparticles by sol–gel method. Tartaric acid is the main acid present in grapes and red wine.

Application

D-(-)-Tartaric acid has been used in the near-field, terahertz time-domain spectroscopic (THz-TDS) analysis of waveguides filled with polycrystalline D-tartaric acid, and with polyethylene and silicon powders.

D-(−)-Tartaric acid may be used in the synthesis of the HIV-protease inhibitor nelfinavir. It may be used in the synthesis of chiral aziridine derivative, a common intermediate for the synthesis of hydroxyethylamine class HIV protease inhibitors such as saquinavir, amprenavir, or nelfinavir.
