Development And Validation Of Uv-Visible Spectrophotometric Method For The Determination Of Chloramphenicol In Pure And In Its Dosage Form

A simple, pecise, rapid sensitive and accurate spectrophotometric methods have been developed for the estimation of Chloramphenicol UV in pure form and its pharmaceutical formulations based on oxidative complexation reaction UV with 1, 10-Phenanthroline reagent at pH - 4 which is extractable at 510 nm. Beer's law is obeyed in the concentration range 0.5-3 ml (5 to 30 mu g ml(-1)). The developed method was applied directly and easily for the analysis of the pharmaceutical formulations. RSD was found to be 0.0185% and recovery 99.73% respectively. The method was completely validated and proven to be rugged. The interferences of the ingredients and excipients were not observed. The repeatability and the performance of the proved method were established by point and internal hypothesis and through recovery studies.
