High Performance Liquid Chromatographic Analysis of Rifampin and Related Impurities in Pharmaceutical Formulations |
| |
Abstract: | Abstract High pressure liquid chromatography was employed for the assay of rifampin in capsules. A reverse phase RP-2 column and a mobile phase of 48% methanol, 5% tetrahydrofuran and 47% 0.05 M ammonium formate (pH 7.3) were used with detection at 254 nm. Rifampin was separated from all its major degradation products and quantitated. |
