D(-)-Tartaric acid 526-83-0 C4H6O6

----------PRODUCT INFORMATION----------

Due to the presence of two identical asymmetric carbon atoms in tartaric acid molecules, it has three optical isomers: right-handed tartaric acid [L (+) - tartaric acid], left-handed tartaric acid [D (-) - tartaric acid], and racemic tartaric acid (Meso). Mixing equal amounts of left-handed tartaric acid with right-handed tartaric acid yields racemic tartaric acid or DL tartaric acid. L-tartaric acid and D-tartaric acid are enantiomers. The naturally occurring tartaric acid is right-handed. Chemicalbook is a colorless transparent crystalline or white fine to granular crystalline powder. Crystalline products contain 1 molecule of crystal water, odorless, stable in air, with an acidic taste and a threshold acidity of 0.0025%. The acidity intensity is about 1.2-1.3 times that of citric acid, and the taste is slightly astringent. There is a foul odor of roasted sugar when burned, and it has a metal ion chelating effect. 1g is approximately dissolved in 0.8mL of water (25 ℃), 0.5mL of boiling water, and 3mL of ethanol. The pH of a 0.3% aqueous solution is 2.4.
