有二个不对称碳原子，有四种立体异构体，即：右旋型（D型， L型）、左旋型（L型，D型）、内消旋型、外消旋型。通常，外消旋型酒石酸又称为葡萄酸。右旋型酒石酸以游离的或K盐、Ca盐、Mg盐的形态广泛分布于高等植物中，特别是多存在于果实和叶中。。等量右旋体和左旋体的混合物的旋光性相互抵消，称为外消旋酒石酸。内消旋体不存在于自然界中，可由化学合成。各种酒石酸都是易溶于水的无色结晶。水中溶解度: 1394 g/L (20℃)。 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 solgel method.Tartaric acid is the main acid present in grapes and red wine. 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. product description： Tartaric acid is a polyhydroxy acid with wide applications in the textile, pharma, and food industries. It is commonly used as a food additive and acts as an antioxidant and acidification agent. It is also used as a starting material for the preparation of many bioactive molecules. application： 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.
