General description
L-(+)-tartaric acid is an organic compound that is commonly used as a chiral auxiliary in reactions that involve the addition of a chiral nucleophile. It is also used as a resolving agent for the separation of enantiomers from a racemic mixture. Additionally, L-(+)-tartaric acid can also be used as a building block for the synthesis of other chiral compounds.
Application
L- (+)-Tartaric acid can be used as:
- A co-former for the synthesis of etravirine co-crystals.
- A mobile phase additive in thin-layer chromatography.
