Spectrophotometric Methods for Determination of Dopamine Hydrochloride in Bulk and in Injectable Forms.

Two highly simple, economical, accurate and sensitive spectrophotometric methods for determination of dopamine hydrochloride (DAH) in either pure form and pharmaceutical formulations are described. The first method is based on determination of (DAH) spectrophotometrically at maximum absorbance 280 nm (method A). The second one is based on reduction of alkaline KMnO by (DAH) leading to the formation of green manganate species which are measured at 610 nm (method B).
