Development and Validation of a New HPLC Method for the Estimation of Sulfamoxole in Bulk and Tablet Formulations

To quantify the sulfamoxole content in bulk as well as tablet formulation, a new isocratic RP-HPLC method was developed and then validated. Kromasil C18 column with a dimension of 250 X 4.6mm was used which was filled with a particle size of 5μ. A mixture containing CH₃OH, CH₃CN and H₂O in the volume ratio of 55, 30 and 15 was used as a mobile phase at room temperature with an optimized flow rate of 1ml/min. UV detector was set at 241nm for sulfamoxole determination. The run time of the current method is ten minutes. Accomplished the forced degradation studies to understand the stability indicating nature of the current method. As per the current ICH guides (Q2R1), validation of the method was conducted.
