Product Details

Tartaric Acid CAS#147-71-7

There are three stereoisomers of tartaric acid: dextrose tartaric acid, levophyllic acid and meso tartaric acid. The optical rotation of the mixture of the same amount of dextrorotatory and levorotism is mutually offset, known as racemic tartaric acid. The mesomer does not exist in nature and can be synthesized chemically. Various tartaric acids are colorless crystals that are easily soluble in water.

Product Application of Tartaric Acid CAS#147-71-7

D-(-)-tartaric acid is widely used as an acidifier in beverages and food, similar to citric acid. It can also be used as a mordant for acid dye when combined with tannin. In the photographic industry, tartaric acid is used for some development and fixing processes. Its iron salts are photosensitive, making them suitable for blueprint production. Tartaric acid has the ability to form complexes with various metal ions, making it effective as a cleaning and polishing agent for metal surfaces. Potassium tartrate, known as Rochelle salt, is used to prepare Fehling reagent and is also employed as a laxative and diuretic in medicine. It is used as an intermediate for the synthesis of quinophan. Due to its piezoelectric properties, tartaric acid crystals find application in the electronics industry.
