B. Starczewska, Spectrophotometric studies and application of imipramine-eriochrome cyanine R system for determination of imipramine in pharmaceuticals, J PHARM B, 23(2-3), 2000, pp. 383-386
Eriochrome cyanine R (ECR) has been tested as reagent for the determination
of imipramine. it reacts in neutral medium with imipramine forming reddish
compound, which can be quantitatively extracted into n-butanol. This prope
rty has been successfully used for the extractive-spectrophotometric determ
ination of imipramine. Beer's law is obeyed in concentration range of 10-80
mu g: ml(-1) of imipramine. The method was applied to the determination of
imipramine in its pharmaceutical. (C) 2000 Elsevier Science B.V. All right
