Tartaric acid crystals drawn as if seen through an optical microscope. Naturally occurring form of the acid is dextro tartaric acid or L-(+)-tartaric acid (obsolete name d-tartaric acid). Because it is available naturally, it is cheaper than its enantiomer and the meso isomer. The dextro and levo prefixes are archaic terms. [15]
A tartrate is a salt or ester of the organic compound tartaric acid, a dicarboxylic acid.The formula of the tartrate dianion is O − OC-CH(OH)-CH(OH)-COO − or C 4 H 4 O 6 2−. [1]The main forms of tartrates used commercially are pure crystalline tartaric acid used as an acidulant in non-alcoholic drinks and foods, cream of tartar used in baking, and Rochelle salt, commonly used in ...
Diethyl tartrate is an organic compound with the formula (HOCHCO 2 Et) 2 (Et = ethyl). Three stereoisomers exist, R,R-, S,S-, and R,S (=S,R-). They are the ethyl esters of the respective R,R-, S,S-, and R,S-tartaric acids. The R,R- and S,S- isomers are enantiomeric, being mirror images. The meso stereoisomer is not chiral. The chiral isomer is ...
They are derived from d,l-tartaric acid, an inexpensive C 2-symmetric molecule. Condensation of dimethyl ester of d,l-tartaric acid with acetone gives the acetonide, a particular kind of dioxalane. The ester groups are susceptible to reaction with aryl Grignard reagents, leading after hydrolysis to the diol. [2]
Dibutyl tartrate is a di-ester of tartaric acid and butanol. [1] It has been used as a chiral oil to separate enantiomers in chromatography. [2] [3] Another use is in farinographs. [4] Yet another use is as a plasticizer. [5] The material is classed as "green" as it is made from natural products, and is biodegradable. [6]
Bitartrate is an anion which is the conjugate base of tartaric acid. It may also refer to any salt or monoester of tartaric acid. Some examples of bitartrate salts include: Choline bitartrate; Cysteamine bitartrate; Dihydrocodeine bitartrate; Dimethylaminoethanol bitartrate; Hydrocodone bitartrate; Metaraminol bitartrate; Norepinephrine ...
It is a white crystalline powder with an acid taste. [1] It is hygroscopic when exposed to air. [ 1 ] Modern texts refer to the choline salt of the natural form of tartaric acid , that is, the salt called choline dextrobitartrate, choline (2 R ,3 R )-bitartrate or choline L-(+)-bitartrate.
The white packets contained tartaric acid, and the blue packets contained a mixture of 75% w/w Rochelle salt (potassium sodium tartrate) and 25% baking soda (sodium bicarbonate). The powdery contents of both packets were stirred or dissolved separately in water and then mixed, giving off carbon dioxide with a characteristic fizzing sound. [ 3 ]
