Product Name:D-Tartaric acid
English Name:D-Tartaric acid
CAS No.:147-71-7
Aliases:D-2,3-Dihydroxysuccinic acid, Dextrotartaric acid, D(-)-Tartaric acid, Unnatural tartaric acid, (2S,3S)-(-)-Tartaric acid, D-Threaric acid
Molecular Formula:C4H6O6
Physical Properties:White crystalline powder, odorless with a sour taste. Density 1.76 g/cm³, melting point 168-170°C. Freely soluble in water (approximately 139 g/100 mL at 20°C), soluble in ethanol, slightly soluble in diethyl ether. Aqueous solution is acidic, specific rotation [α]D²⁰ = +12° (20% aqueous solution).
Uses:Primarily used as an acidulant in the food industry, widely applied in soft drinks, candies, fruit juices, sauces, baking powder, and as a foaming agent and flavor corrective in beer. In the pharmaceutical industry, it serves as a resolving agent for chiral drugs and racemic mixtures. It is also used as a biochemical reagent and in photography, canning, textile dyeing, and ceramics manufacturing.
