Description

General description

L-(+)-Tartaric acid is an organic acid naturally found in grapes and wines. It is widely used as flavoring agent and antioxidizing agent for various beverages (grape juices and wines). It can be synthesized starting from L-ascorbic acid (AA, vitamin C). Its forms various hydrogen-_L-tartrate salts, which have important applications in crystal engineering studies. Its quantification in grape juice has been carried out by recording HPLC chromatograms.

Application

L-(+)-Tartaric acid may be employed as starting reagent in the synthesis of enantiomeric forms of pyrrolidinoisoquinoline derivatives.
