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 ...
Unlike other chemical formula types, [a] which have a limited number of symbols and are capable of only limited descriptive power, structural formulas provide a more complete geometric representation of the molecular structure. For example, many chemical compounds exist in different isomeric forms, which have different enantiomeric structures ...
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.
It is a white powder. Modern texts refer to the N,N-dimethylethanolamine salt of the natural form of tartaric acid, that is, the salt called N,N-dimethylethanolamine dextrobitartrate, N,N-dimethylethanolamine (2R,3R)-bitartrate or N,N-dimethylethanolamine L-(+)-bitartrate.
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]
Potassium sodium tartrate tetrahydrate, also known as Rochelle salt, is a double salt of tartaric acid first prepared (in about 1675) by an apothecary, Pierre Seignette, of La Rochelle, France. Potassium sodium tartrate and monopotassium phosphate were the first materials discovered to exhibit piezoelectricity. [3]
