Description

General description

Tartaric acid is a polyhydroxy acid with wide applications in the textile, pharma, and food industries. It is commonly used as a food additive and acts as an antioxidant and acidification agent. It is also used as a starting material for the preparation of many bioactive molecules.

Application

D-(-)-Tartaric acid may be used in the preparation of enantiospecific homochiral cis-4-formyl β-lactams. It may also be used as a starting material in the synthesis of D-erythro-sphingosine and L-lyxo-phytosphingosine.
