Applications

L-(+)-Tartaric acid is widely utilized in pharmaceutical industries. It is used in soft drinks, confectionaries, food products, gelatin desserts and as a buffering agent. It forms a compound, TiCl<sub>2</sub>(O-i-Pr)<sub>2</sub> with Diels-Alder catalyst and acta as a chelate agent in metal industries. Owing to its efficient chelating property towards metal ions, it is used in farming and metal industries for complexing micronutrients and for cleaning metal surfaces, respectively.

Notes

Incompatible with oxidizing agents, bases and reducing agents.
