Chemical Name: L(+)-2,3-dihydroxy butanedioic acid

Molecular formula: C4H6O6

Molecular weight: 150.09


Character: Colorless or translucent crystals, or a white, fine togranular, crystalline powder. It is odorless, has an acid taste. and is stable in air.

Uses: L(+)-Tartaric acid is widely used as acidulant in beverage, and other foods, such as soft drinks, wine, candy, bread and som colloical sweetmeats, With its optical activity, L(+)-Tartaric acid is widely used as chemical resolving agent to resolve DL-amino-butanol, an intermediate for antitubercular drug. And it is used as chiral pool to synthesize tartarate derivatives. With its acidity, it is used as catalyst in the resin finishing of polyester fabric or pH value regulator in oryzanol production. With its complexation, L(+)-Tartaric acid is used in electroplating, sulfur removal and acid picking. It is also used as complexing agent, screening agent or chelating agent in chemical analysis and pharmaceutical inspection, or as resist agent in dyeing. With its reduction, it is used as reductive agent in manufacturing mirror chemically or imaging agent in photograpjy. It can also complex with many kinds of metal ion and can be used as cleaning agent or polishing agent of metal surface.
