Reduction and Determination of 1‐[2‐Phenyl‐2‐(hydroxyimino)‐ethyl]‐6‐methylquinolinium Chloride on the Dropping Mercury Electrode
(Archiv der Pharmazie, 1987)
The polarographic behavior of 1‐[2‐phenyl‐2‐(hydroxyimino)ethyl]‐6‐methylquinolinium chloride has been investigated. The pH of the Britton‐Robinson buffer, used as supporting electrolyte, influences the position of the ...
Spectrophotometric determination of some theophylline derivatives
(Acta Pharmaceutica Jugoslavica, 1988)
A spectrophotometric method for the determination of 8-chlorotheophylline, diprophylline and oxyethyltheophylline, is presented. Spectrophotometric determinations were carried out in CH3OH, 0.5 mol dm-3 H2SO4 4.65 mol dm-3 ...
