Abstract

A spectrophotometric method for the determination of propranolol hydrochloride (PP) was established by using the Bromopyrogallol Red (BPR)-molybdenum(VI) complex. This method can be used to determine 1.5 similar to 30 mug/10 ml PP; the apparent molor absorptivity is 7.8 x 10(4) l mol(-1) cm(-1) at618 nm. The proposed method was applied to assays of PP in pharmaceutical preparations (tablet, extend-release capsule and injection). Moreover, thismethod could be applied to the assay of drugs, such as chlorpromazine and alprenolol. The analytical results and recoveries were satisfactory.
