L(+)-Tartaric acid is widely used as acidulant in
beverage,and other foods, such as soft drinks, wine,
candy, bread and some colloidal sweetmeats. With
its optical activity, L(+)-Tartaric acid is used as
chemical resolving agent to resolve DL-aminobutanol, an intermediate for antitubercular drug. And
it is used as chiral pool to synthesize tartrate
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 pickling. 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 photography. It can also complex with metal
ion and can be used as cleaning agent or polishing
agent of metal surface.
