application | 4,4-bipyridine dihydrochloride can be used as an intermediate in pharmaceutical synthesis and an intermediate in organic synthesis, mainly used in laboratory research and development and chemical pharmaceutical synthesis. |
use | 4,4-bipyridine dihydrochloride can be used as an intermediate in pharmaceutical synthesis, such as preparing [Nd(NO3)3(CH3OH)2(4,40-bipyridine) 2]: slowly pour 4 into Nd(NO3)36H2O(0.1096g,0.25mmol) methanol solution (10 cm3), 4-methanol mixture of bipyridine dihydrochloride (0.0781g,0.5mmol) and pyrazine (0.020g,0.25mmol). Stir the whole mixture for 30 minutes, then slowly evaporate in an open atmosphere. After 2 weeks, a transparent clove block suitable for X-ray structural study was obtained. These crystals were separated, washed with methanol and dried (yield: 67%, based on Nd). |
