Products Description of Tartaric acid CAS# 133-37-9

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.

Product Application of DL-Tartaric acidCAS#133-37-9

DL-Tartaric acid is used as a synergist for antioxidants, emulsifier, sequestrant and flavoring agent. It is also added with citric acid to prepare effervescent salts, thereby enhancing the taste of oral medications. It is also utilized in pigments, processing aids, ink, toner and colorant products. It acts as a chelating agent in metal and farming industries. Further, it is used as lubricant and grease. It is mixed with sodium bicarbonate and used as a leavening agent in food preparation. In the pharmaceutical industry, it is utilized in the preparation of tartar emetic, which is used in cough syrup as an expectorant.
