Abstract
Thiamine monophosphate disulfide (TMPDS) is obtained by the oxidation of thiamine monophosphate in alkaline solution. As oxidizing agents halogens, hydrogenperoxide and ferricyanide can be used. TMPDS is soluble in water, slightly soluble in methanol and ethanol, insoluble in other organic solvents (ether, benzene, acetone). Polymorphisms of TMPDS are shown in Tab. 2 and Fig. 2. Metallic salts of TMPDS are shown in Tab. 3.
