H. S Code: 29181200 00

Molecular weight: 150.09

Chemical Properties: DL-Tartaric acid is a water- and alcohol-soluble colorless crystalline solid with a characteristic acid taste and a melting temperature of 170°C(338°F). Naturally occurring tartaric acid is generally of the L-configuration (based on the absolute configuration of D-glyceric acid). The L-forms of tartrates are dextrorotatory in solution and thus are designated as L(+)-tartrates. It is also known as dihydroxy succinic acid. Tartaric acid is used as a chemical intermediate and a sequestrant,as well as in tanning, effervescent beverages, baking powder, ceramics, photography, textile processing,mirror silvering,and metal coloring.

Appearance: Colorless or translucent crystals, or a white, fine granular, crystalline powder. It is odorless, has an acid taste, and is stable in air.

Package: 25 kg net in the composite paper-plastic bag.

Application: Used as an acidulate in beverage and food, such as candy, soft drink, wine, bread, and some colloidal sweetmeats; Also used as complexion agent, screening agent or chelating agent in chemical analysis and pharmaceutical inspection, or as resist agent in dyeing.
