Application of 4,4ˊ-bipyridine dihydrochloride_Industrial additives

Application background and overview of 4,4ˊ-bipyridine dihydrochloride

4,4ˊ-Bipyridine dihydrochloride can be used as a pharmaceutical synthesis intermediate and an organic synthesis intermediate. It is mainly used in laboratory research and development processes and chemical and pharmaceutical synthesis processes. If 4,4ˊ-bipyridyl dihydrochloride is inhaled, move the patient to fresh air; if skin contact occurs, take off contaminated clothing, rinse the skin thoroughly with soap and water, and seek medical attention if you feel unwell; if In case of eye contact, separate eyelids, rinse with running water or saline, and seek medical attention immediately; if ingested, rinse mouth immediately, do not induce vomiting, and seek medical attention immediately.

Applications of 4,4ˊ-bipyridine dihydrochloride

4,4ˊ-Bipyridyl dihydrochloride can be used as a pharmaceutical synthesis intermediate, such as preparing [Nd(NO3)3(CH3OH)2(4,40-bipyridyl)2]: To Nd(NO3)36H2O (0.1096g, 0.25mmol) in methanol solution (10cm3) was slowly poured into the methanol mixture of 4,4ˊ-tetrahydrofuranbipyridine dihydrochloride (0.0781g, 0.5mmol) and pyrazine (0.020g, 0.25mmol). The entire mixture was stirred for 30 minutes and then evaporated slowly in an open atmosphere. After 2 weeks, a transparent clove block suitable for X-ray structural study was obtained from cyclohexylamine carbonate. The crystals were isolated, washed with methanol and dried (yield: 67%, based on Nd). Anal. Calcd for C22H24N7NdO11: C, 37.39; H, 3.42; N, 13.87. Actual measured values: C, 37.45; H, 3.37; N, 14.01%.
