CRYSTALLOGRAPHIC CHARACTERIZATION OF TRANS ESTERIFIED POTENTIAL IMPURITY OF CANDESARTAN
Abstract
The title compound (CDC II), C28H28N6O3, is a potential impurity found in commercial product candesartan cilexetil, consist of N- ethylation of tetrazole moiety attached to biphenyl ring, selectively at N-6 position. The Crystal structure held together by C脙聝脗炉脙聜芒聜卢脙聜脗颅H脙聝脗炉脙聜脝聮脙聜芒聙聰脙聝脗炉脙聜脝聮脙聜芒聙聰脙聝脗炉脙聜脝聮脙聜芒聙聰O intermolecular interactions. Crystal structure of the title compound was obtained by single crystal X-ray diffraction which was crystallizes in the monoclinic space group P21/n with cell parameter a = 12.1574(12)Å, b = 13.9178(14)Å,c = 15.9742(19)Å and Z = 4.
