Pawlaczyk, Jan published the artcileMineral contamination of drugs. I. Application of spectrography and atomic absorption spectrometry to the analysis of metal ion traces, SDS of cas: 2508-72-7, the publication is Acta Poloniae Pharmaceutica (1979), 36(1), 59-62, database is CAplus and MEDLINE.
Ca, Ag, Cu, Al, Bi, Ni, Fe, Mg, Pb, and Zn ions were the most abundant contaminants in phenylbutazone [50-33-9], Na aminosalicylate [133-10-8], carbromal [77-65-6], methylphenobarbital [115-38-8], chlorpromazine-HCl [69-09-0], Et aminobenzoate [94-09-7], nitrofurantoin [67-20-9], glutethimide [77-21-4], antazoline-HCl [2508-72-7], barbital [57-44-3], phenytoin [630-93-3], and bromisoval [496-67-3] preparations In some cases, the levels of the contaminants were determined by at. absorption spectrometry upon mineralization or extraction with HCl.
Acta Poloniae Pharmaceutica published new progress about 2508-72-7. 2508-72-7 belongs to imidazoles-derivatives, auxiliary class Inhibitor,Immunology/Inflammation,Histamine Receptor, name is N-Benzyl-N-((4,5-dihydro-1H-imidazol-2-yl)methyl)aniline hydrochloride, and the molecular formula is C17H20ClN3, SDS of cas: 2508-72-7.
