D-(-)-Tartaric Acid CAS 147-71-7

Chemical Formula: C4H6O6
Molecular Weight: Approximately 150.09 g/mol
CAS Number: 147-71-7
Physical Properties: D-(-)-Tartaric acid is a white, crystalline powder with a sour taste.
Solubility: It is soluble in water and alcohol, while has limited solubility in organic solvents.

D-(-)-Tartaric acid is the D-enantiomer of tartaric acid. It is an enantiomer of a L-tartaric acid.

There are three stereoisomers of tartaric acid: dextrose tartaric acid, levophyllic acid and meso tartaric acid. D-(-)-Tartaric acid (dextrose tartaric acid) is a naturally occurring organic acid that belongs to the class of tartaric acids. It is the enantiomer of L-(+)-tartaric acid. The prefix “D-” indicates the stereochemistry of the molecule, specifically its configuration as the dextrorotatory form.

D-(-)-Tartaric Acid CAS 147-71-7 Use:

  • D-(-)-Tartaric acid acts as a resolving agent in organic synthesis. It is a precursor for the preparation of its ester derivatives like D-tartaric acid diethyl ester.
  • Similar to citric acid, D-(-)-tartaric acid is commonly employed as an acidifier in food and beverages.
  • When combined with tannin, it can also function as a mordant for acid dyes.
  • Tartaric acid is utilized in the photographic industry for certain fixing and development procedures. Because its iron salts are photosensitive, they can be utilized in the fabrication of blueprints.
  • Tartaric acid possesses the capability of establishing complexes with a wide range of metal ions, rendering it an efficacious agent for the cleansing and polishing of metal surfaces.
  • The electronics industry utilizes tartaric acid crystals owing to their piezoelectric characteristics.
  • It is widely utilized in the food industry as a flavoring agent, beer froth agent, and acidity regulator.
