A simple and inexpensive method was developed with high performance liquid chromatography with PDA detection for determination of Terbinafine HCl and related impurities. The chromatographic separations were achieved on (150×4.6 mm), 5.0 μm make: YMC-Pack ODS-AM, 120A column employing Acetonitrile: methanol and Water pH 7.5, in the ratio of 20:10:10 v/v/v as mobile phase with gradient programmed at flow rate 1.0 mL/min was chosen. Three impurities were eluted within 35 minutes. The detector wavelength of 230 nm was employed.
