Used as a chiral starting materialreagent in organic synthesis especially for preparing optically active compounds and pharmaceuticals.

Helps introduce or control stereochemistry (chirality) during chemical synthesis and is commonly used in asymmetric synthesis.

Diethyl L-()-tartrate is the diethyl ester of L-()-tartaric acid a chiral organic compound. It is typically used as a colorless to pale-yellow liquidreagent in laboratory and industrial synthesis.
