Abstract：
: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 property has been successfully used for the extractive-spectrophotometric determination of imipramine. Beer's law is obeyed in concentration range of 10-80 microg ml(-1) of imipramine. The method was applied to the determination of imipramine in its pharmaceutical.
