| 产品描述: | 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. |
