A VALIDATED STABILITY-INDICATING HPLC ASSAY METHOD FOR ACYCLOVIR IN BULK DRUG

An isocratic reversed phase stability-indicating high-performance liquid chromatographic (HPLC) assay method was developed and validated for quantitative determination of Acyclovir in bulk drugs. An isocratic, reversed phase HPLC method was developed to separate the drug from the degradation products, using an Water Nova Pack C18 (250 x 4.6) mm, 5µ column and the mobile phase containing 1.0gm Sodium dihydrogen phosphate and 1.0 gm 1-octaneSulfonic acid salt in 1000ml water filter and mixed. Prepare a homogenous mixture of buffer, methanol and acetonitrile (50:20:30,v/v/v). The detection was carried out at wavelength 264 nm. The developed method was validated with respect to linearity, accuracy (recovery), precision, system suitability, selectivity, robustness prove the stability indicating ability of the method.
