The drug was susceptible to acid - base hydrolysis, oxidation and dry heat degradation. Also the degraded products were well separated from the pure drug with significantly different Rf values. Quantitative determination by absorbance measurement at 230 nm. The linear regression data for the calibration plots showed good linear relationship with r2=0.999 in the concentration range of 200-1000 ng. The mean value of correlation coefficient, slope and intercept were 0.999±0.001, 0.093±0.011 and 8.83±0.99, respectively. The method was validated for precision, accuracy, ruggedness and recovery. The limits of detection and quantitation were 40 and 120 ng per spot, respectively.
