White solid | [Uses]
Reagent for the quantitative reduction of disulfide group. Prevents the oxidation of cholecystokinin during its extraction from brain and duodenal tissues. Cleavage of disulfide bonds in proteins. | [Definition]
ChEBI: D-1,4-dithiothreitol is a 1,4-dithiothreitol. It is an enantiomer of a L-1,4-dithiothreitol. | [Preparation]
The preparation of DL-Dithiothreitol is as follows:To a round bottom flask was charged THPP (23mg, 0.11mmol, 1.10eq) and the basic buffer solution [tris-(hydroxymethyl)-aminomethane-CaCl2 based buffer; pH 8.00; 1.0mL]. The reaction mixture was stirred at room temperature for about 5 min and then to this homogenous solution was charged trans-4,5-Dihydroxy-1,2-dithiane (15.2mg, 0.10 mmol, 1.00eq.). The reaction mixture was stirred at room temperature until the reaction was complete (about 30 min). The product was readily identified by 1H-NMR analysis. | [Purification Methods]
Crystallise DTT from ether and sublime it at 37o/0.005mm. It should be stored at 0o. [Beilstein 1 III 2360.] |
