| Application: |
it is widely used as acidulant in beverage,and other foods.
It is also used as chemical resolving agent to resolve DL-amino-butanol,
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.
