2,4-Dinitrophenylrhodanide Thiocyanic Acid 2,4-Dinitrophenyl Ester - Uses and synthesis methods
| introduction | dinitrosan is an organic compound, which is mainly used as an intermediate in organic synthesis, as well as synthetic drugs and biochemical analysis. Phenyl isothiocyanate (PITC) is used to react with the N-terminal amino group of the polypeptide to be analyzed under basic conditions to generate derivatives of phenylaminothioformamide (PTC), which are then treated with acid, closed, and the N-terminal of the peptide chain is selectively cut off to obtain the N-terminal amino acid residue of thiazolinone aniline derivatives. |
| preparation | in a reaction container equipped with a stirrer, a thermometer and a reflux condenser, 2, 4-dinitrobenzene (2)0.32mol, the mass fraction is 500ml of 60% cyclohexane, 0.31mol of stannous chloride and 0.51mol of thiocyanamine solution are added, the stirring speed is controlled to 150rpm, the solution temperature is increased to 80 ℃, the reflux is maintained for 5h, the solution temperature is reduced to 5 ℃, and, the water layer was extracted with 70% acetonitrile, combined with organic layer, washed with ammonium nitrate solution, washed with 80% ethylenediamine, dehydrated with activated alumina, recrystallized in 90% nitromethane to obtain 52.26g crystalline thiocyanate -2, 4-dinitrophenyl ester with 73% yield. |
