L(+)-Tartaric Acid

L(+)-Tartaric acid is colorless or translucent crystals, or a white, fine granular, crystalline powder. It is odorless, has an acid taste, and is stable in air.

L(+)-Tartaric acid is widely used as an acidulant in beverage and other foods. With its optical activity, L(+)-Tartaric acid is used as a chemical resolving agent to resolve DL-amino-butanol, an intermediate for the antitubercular drug. And it is used as a chiral pool to synthesize tartrate derivatives. With its acidity, it is used as a 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 pickling. It is also used as a complexing agent, food additives screening agent or chelating agent in chemical analysis and pharmaceutical inspection, or as resist agent in dyeing. With its reduction, it is used as a reductive agent in manufacturing mirror chemically or imaging agent in photography. It can also complex with metal ion and can be used as a cleaning agent or polishing agent of the metal surface.
