Abstract
A simple and sensitive spectrophotometric method has been developed for the determination of some dibenzazepines, based on reaction with picryl chloride in chloroform medium and measurement at 395 nm. Beer's law is obeyed in concentration ranges 0.1–1.0 μg/ml for imipramine hydrochloride, trimipramine maleate and opipramol dihydrochloride, 0.16–1.6 μg/ml for desipramine hydrochloride and 0.4–2.4 μg/ml for clomipramine hydrochloride. The method was applied successfully to the determination of dibenzazepines in tablets and the results were comparable to those obtained by official procedures.
