Sane, R. T. published the artcileExtractive spectrophotometric determination of antazoline hydrochloride, maphazoline nitrate, xylometazoline hydrochloride and tetrahydrozoline hydrochloride, Recommanded Product: N-Benzyl-N-((4,5-dihydro-1H-imidazol-2-yl)methyl)aniline hydrochloride, the publication is Indian Drugs (1979), 16(10), 239-41, database is CAplus.
A direct spectrophotometric method for the quant. determination of antazoline-HCl (I) [2508-72-7], naphazoline nitrate [5144-52-5], xylometazoline-HCl [1218-35-5], and tetrahydrozoline-HCl [522-48-5] is described. The method is based on the formation of colored complexes between these compounds and bromocresol green, bromophenol blue, bromothymol blue, and methyl orange. The complexes formed can be extracted in chloroform.
