Tartaric Acid Commodity: L(+)-Tartaric Acid Molecular Formula: C4H4O6 CAS Number: 87-69-4(Standard:FCCIV,1996) Chemical structure: Property: Colorless or translucent crystals, or a white, fine granular, crystalline powder. It is odorless, has an acid taste, and is stable in air. Packing and storage: 25KG net in Kraft/Plastic Bag lined with PE bag, 20MT/20FCL (on pallet). Kept air tightly in a light-proof, dry and cool place. Application: L(+)-Tartaric acid is widely used as acidulant in beverage, and other foods, such as soft drinks, wine, candy, bread and some colloidal sweetmeats. With its optical activity, L(+)-Tartaric acid is used as chemical resolving agent to resolve DL-amino-butanol, an intermediate for ant tubercular drug. And it is used as chiral pool to synthesize tartrate derivatives. With its acidity, it is used as catalyst in the resin finishing of polyester fabric or pH value regulator in oryzanol production. With its complexation, L(+)-Tartaric acid is used in electroplating, sulfur removal and acid pickling. Specification and analysis data See the table below.
