The present study is aimed to develop visible spectrophotometric methods for the determination of Bendamustine hydrochloride. The developed methods involve the formation of chloroform extractable colored ion-association complexes of Bendamustine hydrochloride with tropaeolineo-oo (Method A) and Alizarin Red S (Method B). The chloroform extracted coloured complexes showed absorbance maxima at wavelengths 480 and 460nm in methods A and B respectively.  Beer’s law obeyed in the concentration range of 2.5–12.5μg/mL in both the cases. Correlation coefficients were found to be 0.9991 and 0.9998 for methods A and B respectively. In addition molar absorptivity, Sandell sensitivity and the optimum conditions for quantitative analysis of the Bendamustine hydrogenchloride were determined.  The developed ion-association complex methods were rapid, simple and economically viable compared to other reported analytical methods which require expensive instruments and are not available in common laboratories. Thus the proposed methods for Bendamustine determination in bulk and pharmaceutical formulations can be used in commercial laboratories.
