Liquid chromatographic determinations of meta-chlorobenzoic acid in bupropion hydrochloride
A simple, sensitive method for the determination of meta-chlorobenzoic acid in bupropion hydrochloride is described. Chromatographic separation of m-chlorobenzoic acid is achieved using a mobile phase consisting of n-hexane and ethanol (1000:50, v/v) at a flow rate of 1.0 ml/min on a Chiralpak ADH (...

| Sumario: | A simple, sensitive method for the determination of meta-chlorobenzoic acid in bupropion hydrochloride is described. Chromatographic separation of m-chlorobenzoic acid is achieved using a mobile phase consisting of n-hexane and ethanol (1000:50, v/v) at a flow rate of 1.0 ml/min on a Chiralpak ADH (250 × 4.6 mm). Absorbance is monitored at 235 nm. The method is linear for m-chlorobenzoic acid over concentration range of LOQ, 5.0 μg/ml to 15.0 μg/ml for m-chlorobenzoic acid with correlation coefficient greater than 0.99. This method is more selective and accurate than United States Pharmacopoeia method for the determination of m-chlorobenzoic acid in bupropion hydrochloride. |
