Main functions and uses

L(+)-tartaric acid is widely used as a sour agent in beverages and other foods for soft drinks, red wine, candy, bread, and some gelatinous confections. Using its optical activity as a chemical resolving agent for the resolution of DL-aminobutanol, an anti-tuberculosis drug intermediate; it can also be used as a chiral raw material for the synthesis of tartaric acid derivatives; using its acidity as a polyester fabric resin Finished catalyst, pH regulator produced by oryzanol; using its complexability, used as a complexing agent, masking agent, chelating agent, printing and dyeing anti-dyeing agent in electroplating, desulfurization, pickling, chemical analysis, medical examination; Its reducibility, used as a reducing agent for chemical mirroring. Photographic developer. It can also be complexed with various metal ions and can be used as a cleaning agent and polishing agent for metal surfaces. L(+)-tartaric acid is also the best retarder for self-leveling cement and gypsum industry.
