<span style="font-size:14px;"><strong>Important derivatives of tartaric acid include its salts, cream of tartar (potassium bitartrate), Rochelle salt (potassium sodium tartrate, a mild laxative), and tartar emetic (antimony potassium tartrate). Diisopropyl tartrate is used as a co-catalyst in asymmetric synthesis.</strong></span></p>

<span style="font-size:14px;"><strong>100 µg/mL (e), 125 µg/mL (f) dosage of Cu2O NPs and untreated control (d). ... modified with carboxylic acid ligands or tartaric/adipic acids demonstrated.</strong></span></p>

The recovered product is washed twice with absolute ether, filtered, and dried. About 7 g. of product, m.p. 129–131°, is thus obtained.</strong></span></div>

<span style="font-size:14px;"><strong>4. The product is not stable and should be prepared only as needed. It may be kept in a vacuum desiccator over phosphorus pentoxide and paraffin, but the melting point drops about 1 degree during the first 4 days and then remains constant at approximately 132–134°. If placed in an ordinary stoppered bottle, the product becomes gummy and the melting point falls to about 100° within 3 days. Attempts to recrystallize the anhydride invariably led to decomposition and lowered melting point.</strong></span></div>
