KEYWORD: Tartaric Acid, D-Tartaric Acid, DL-Tartaric Acid Raw Material, API

Chemical Name: 2, 3-dihydroxybutanedioic acid


Description & Usage:

D-Tartaric Acid exists in loquat. It is found combined as Chicoric acid and it is an unnatural tartaric acid isomer. D-Tartaric acid belongs to the family of Dicarboxylic Acids and Derivatives.

Tartaric Acid occurs naturally in some plants. Commonly known, it is found in grapes, bananas and tamarinds.

Tartaric Acid is used to generate carbon dioxide through interaction with sodium bicarbonate following oral administration.

The naturally occurring form of the acid is L-(+)-tartaric acid or dextrotartaric acid. The mirror-image (enantiomeric) form, levotartaric acid or D-(-)-tartaric acid, and the achiral form, mesotartaric acid, can be made artificially.

Tartaric acid is a muscle toxin. It works by inhibiting the production of malic acid. If highly dosed, it may cause paralysis and death. The minimum recorded fatal dose for a human is about 12 grams.

Salts of tartaric acid are known as tartrates. It is a dihydroxy derivative of dicarboxylic acid.

Tartrates are other additives serving as antioxidants or emulsifiers. Naturally-occurring tartaric acid is chiral. It is a useful raw material in organic chemistry for the synthesis of other chiral molecules. Tartarate is believed to inhibit kidney stone.

Three stereoisomeric forms of tartaric acid exist:

(1) dextrorotatory tartaric acid (d-tartaric acid) found in grapes and several other fruits,

(2) levorotatory tartaric acid (l-tartaric acid) obtained chiefly by resolution of racemic tartaric acid,

(3) a meso or achiral form. Racemic tartaric acid (an equal mixture of d- and l-tartaric acid) is prepared commercially by the molybdenum- or tungsten-catalyzed oxidation of maleic anhydride with hydrogen peroxide.

Usage:

Tartaric Acid is one of the main acids found in wine. It is added to other foods as food additive to give the food a sour taste. Tartaric Acid is included in many foods, especially sour-tasting sweets. As a food additive Tartaric Acid can be used as an antioxidant.

Tartaric acid, also called dihydroxybutanedioic acid , a dicarboxylic acid, one of the most widely distributed of plant acids. It has many food and industrial uses.
