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 ...
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]
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 ...
Potassium bitartrate, also known as potassium hydrogen tartrate, with formula K C 4 H 5 O 6, is a chemical compound with a number of uses. It is the potassium acid salt of tartaric acid (a carboxylic acid). Especially in cooking, it is also known as cream of tartar.
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 ...
Potassium tartrate, dipotassium tartrate or argol has formula K 2 C 4 H 4 O 6. It is the potassium salt of tartaric acid. It is often confused with potassium bitartrate, also known as cream of tartar. As a food additive, it shares the E number E336 with potassium bitartrate. [1]
