Witryna5-Amino-2-chloropyridine was used in the synthesis of [2H5]2-amino-l-methyl-6-phenylimidazo[4,5-b]pyridine. It was used in identification and evaluation of molecularly imprinted polymers for the selective removal of potentially genotoxic aminopyridine impurities from pharmaceuticals. Packaging 1, 5 g in glass bottle Safety Information … WitrynaChloropyridine. ND of 2-amino-5-chloropyridine shows that the molecules are linked into dimers in the crystalline state by NH⋯N amino–pyridine nitrogen bonds of length which can accurately be shown to be 3.058Å between the two nitrogen atoms, 2.015Å for N⋯H, and at an angle of 174° 〈76AX(B)224〉.
