Use | Dithiothreitol (DTT) is a small molecule organic reducing agent with chemical formula C4H10O2S2, which is mainly used in the field of biotechnology as a protein cleavage reagent. At present, the synthesis method of dithiothreitol, which is the most widely used in Chemicalbook, takes thritol as the raw material, first oxidize it with potassium manganese, then obtain thioglycolate intermediate under the action of thioacetic acid, and finally hydrolyze the thioglycolate intermediate to obtain dithiothreitol. |
