Abstract

A simple and cost effective spectrophotometric method is described for the determination of mesalamine in pure form and in pharmaceutical formulations. When the drug reacts with 0.5N HCl shows absorption maximum at 303 nm and obeys beer’s law in the concentration range 10‐50μg mL‐1. The absorbance was found to increase linearly with increasing concentration of MSZ, which is corroborated by the calculated correlation coefficient value of 0.999 (n=6). The apparent molar absorptivity and sandell sensitivity were 1.63 X 1010and 0.0402 μg cm‐2 respectively. The slope and intercept of the equation of the regression line are 0.025 and 0.002 respectively. The limit of detection and limit of quantification was found to be 0.04914 μg mL‐1 & 0.14893 μg mL‐1. The validity of the described procedure was assessed. Statistical analysis of the result has been carried out revealing high accuracy and good precision. The proposed method w as successfully applied to the determination of MSZ in pharmaceutical formulations without any interference from common excipients. The relative standard deviations were ≤0.6536%, with recoveries of 98.65% ‐ 101.05%.
