D-Tartaric acid CAS 147-71-7

D-Tartaric acid CAS 147-71-7 exists in three stereoisomers: tartaric acid, levo-tartaric acid and meso-tartaric acid. The optically active phases of a mixture of equal amounts of dextro- and levorotatory bodies cancel each other out, which is called racemic tartaric acid. Meso does not exist in nature and can be synthesized chemically. All kinds of tartaric acid are colorless crystals that are easily soluble in water..

D-Tartaric acid CAS 147-71-7 Application

Widely used in the food industry, such as beer foaming agent, food sour agent, flavoring agent, used in refreshing drinks, candy, fruit juice, sauce, cold dishes, baking powder, etc.

Tartaric acid is widely used as an acidulant in beverages and other foods, in a similar way to citric acid. Used in combination with tannins, tartaric acid acts as a mordant for acid dyes, and is also used in some developing and fixing operations in the photographic industry, and its iron salts are photosensitizing, making them useful in blueprints. Tartaric acid can complex with a variety of metal ions and can be used as a cleaning agent and polishing agent for metal surfaces. Potassium sodium tartrate (Luo Chemicalbook Shell salt) can be used to prepare Fehling's reagent, and can also be used in medicine as a laxative and diuretic, and also used as an intermediate of Cincophen. Its crystals have piezoelectric properties and can be used in the electronics industry. Mainly used in beverage, candy, bread, gelatin as sour agent, biochemical reagent, racemate splitting agent, pharmaceutical splitting agent. Also used in photography, canning, printing and dyeing, pottery and in the preparation of other resolving agents and salts
