Descripción del producto

Product Description
Tartaric acid is a white crystalline diprotic aldaric acid. It occurs naturally in many plants, particularly grapes, bananas, and tamarinds, is commonly combined with baking soda to function as a leavening agent in recipes, and is one of the main acids found in wine. It is added to other foods to give a sour taste, and is used as an antioxidant. Salts of tartaric acid are known as tartrates. It is a dihydroxyl derivative of succinic acid.

MAIN FUNCTION AND PURPOSE D(-)-tartaric acid is an important chiral pool of 4 carbon atoms. With the rapid development of chiral pharmaceuticals, chiral additives and chiral auxiliaries, D(-)-tartaric acid is more and more widely used in pharmaceuticals and food industry. It is also used as chiral pool or resolving agent for chiral synthesis. 
When D(-)-tartaric acid or its derivatives is used to resolve amino acid, it has some advantages such as high reaction speed, high resolution ratio, and during the period of resolution, the dynamic process can be controlled and can oblige the amino acid to transform to the target configuration. So the yield always reaches *0%. Furthermore, D(-)-tartaric acid is easy to retrieve after resolution. The optical purity of the product is high and e.e% value can reach *9.9%.
In addition, D(-)-tartaric acid has also been widely used in synthesizing and manufacturing many kinds of chiral food additives including the resolution of a new functional nutriment *- L-carnitine, and some chiral pharmaceuticals.
 
PACKING *5kg net weight in Cardboard Drum or according to customer requirements  
STORAGE Kept in a light-proof, well-closed, dry and cool place.


[Application I] L (+) - tartaric acid is widely used as a sour agent in beverages and other foods. [Application 2] It is used as biochemical reagent, masking agent and beer foaming agent, and also used in tanning industry [Use 3] L (+) - tartaric acid is widely used as a sour agent in beverages and other foods, and is used in wine, soft drinks, candy, bread, and some gummed sweets. Using its optical activity, it can be used as a chemical resolution agent for the resolution of DL aminobutanol, an intermediate of anti tuberculosis drugs; It can also be used as chiral raw materials for the synthesis of tartaric acid derivatives; Its acidity is used as a catalyst for resin finishing of polyester fabrics and a PH regulator produced by oryzanol. [Application 4] It is used as a complexing agent, masking agent, chelating agent, and anti dye in electroplating, desulfurization, pickling, chemical analysis, and medical inspection by virtue of its complexing property; Using its reducibility, it can be used as a reducing agent for chemical mirror making. A photographic developer. It can also be complexed with a variety of metal ions, and can be used as a cleaning agent and polishing agent for metal surfaces.
