The sterochemistry of the base was resolved into two isomers by using tartaric acid.
It is a derivative of both caffeic acid and tartaric acid.
Winemakers more often have problems with low acidity levels which require supplementation with additional acids like tartaric acid.
Salts of tartaric acid are known as tartrates.
Examples of so-called chiral resolving agents are tartaric acid and brucine.
Caftaric acid is formed when caffeic acid and tartaric acid undergo esterification.
The racemic mixture may be separated using tartaric acid.
It is an ester formed from ferulic acid bound to tartaric acid.
