Identification of tropacin, tropaphen, homatropine hydrobromide and their degradation products by UV spectra: Identification of tropacin, tropaphen, homatropine hydrobromide and their degradation products by UV spectra. Karpenko, V. A.; Stepanyuk, S. N. (Pyatigorsk. Farm. Inst., Pyatigorsk, USSR). Farmatsiya (Moscow), 33(5), 50-2 (Russian) 1984. CODEN: FRMTAL. ISSN: 0367-3014. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Section cross-reference(s): 63 Tropacin (I) [6878-98-4], tropaphen (II) [15790-02-0], and homatropine (III) [87-00-3] (as III-HBr) and their degrdn. products were identified by UV spectroscopy. I has 3 max. around 245-260 nm and min. 250-258 in the UV spectra in water, CHCl3, 0.1 N HCl, and 0.01N NaOH ethanolic solns., II has 3 max. at 253, 258, 264 nm and a small inflection at 270 nm. III has a max. around 258-259 nm and an inflection at 265 nm in 0.1 N HCl and in 0.01 N NaOH soln. in EtOH. The absorbance values are useful for the identification of the drugs. The degrdn. products, mandelic acid [90-64-2], diphenylacetic acid [117-34-0], and a-phenyl-b-(p-hydroxyphenyl)propionic acid [89-23-6] were also identified by the spectral data.
