  The paper reports an efficient and rapid fast LC method for estimation of diclofenac potassium and its impurities. The main aim of the study is to develop and validate a simple, rapid, accurate, sensitive, less time consuming and less expensive method by using RP-HPLC with UV detector. The chromatographic separation of diclofenac potassium and its impurities was carried out by using 150 × 4.6 mm, i.d., 5 μm C-18 column with prepared mobile phase-A consisting 800:200 (v/v) of 0.01 M ammonium acetate adjusted pH 5.3 with acetic acid and acetonitrile and mobile phase-B consisting 200:800 (v/v) of 0.01 M ammonium acetate adjusted pH 5.3 with acetic acid and acetonitrile. The wavelength for detection of were made at 280.0 nm using UV detector. The flow rate of 1 mL/min. The method was able to detect and separate impurities and diclofenac potassium. The system suitability parameter.. View More»
