L(+)-Tartaric Acid

Product Overview

L(+)-Tartaric Acid (also written L tartaric acid, CAS 87-69-4) is the naturally occurring optically active form of tartaric acid (the 2R,3R or 2S,3S stereochemistry is commonly referenced — L(+)-tartaric is 2R,3R tartaric acid / 2S,3S tartaric acid depending on notation). It is found in grapes, berries and wine and is widely used for its sour taste, antioxidant properties and excellent chelating/buffering behaviour in food, beverage, pharmaceutical and technical applications.

Tartaric acid occurs as colorless monoclinic crystals, or a white or almost white crystalline powder. It is odorless, with an extremely tart taste. L-(+)-Tartaric Acid is a naturally occurring chemical compound found in berries, grapes and various wines. It provides antioxidant properties and contributes to the sour taste within these products.
