Dessouky, Y. M. published the artcileDetermination of some pharmaceutical amines by sodium dioctyl sulfosuccinate, Recommanded Product: N-Benzyl-N-((4,5-dihydro-1H-imidazol-2-yl)methyl)aniline hydrochloride, the publication is Bulletin of the Faculty of Pharmacy (Cairo University) (1979), 16(1), 67-74, database is CAplus.
The conditions of diphasic titration of amines, based on ion-pair formation, were modified and applied to the determination of 7 pharmaceutical amines, e.g., aminopyrine (I) [58-15-1] and promethazine-HCl [58-33-3]. Acetate buffer of pH 0.91 or 0.65 and dimethylyellow screened with methylene blue as indicator were used. The stoichiometry (1:1) of the reaction between Na dioctyl sulfosuccinate [577-11-7] and the amines was determined; this made it unnecessary the need for the side-by-side titration of an authentic sample of the amine. Amounts as low as 0.30 mg could be determined by the modified procedure as against 10 mg by the unmodified procedure. The results obtained with the modified procedure are compared with those of British pharmacopeia(1973) and European pharmacopeia(1971) methods.
Bulletin of the Faculty of Pharmacy (Cairo University) 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, Recommanded Product: N-Benzyl-N-((4,5-dihydro-1H-imidazol-2-yl)methyl)aniline hydrochloride.
