Analytical method validation is the process of proving or documenting that an analytical method produces data that can be used for what it was made for. The main goal of an analytical procedure is to get results that can be repeated and can be trusted and are good enough for the intended purpose. An effective and simple method was developed and validated for quantitative analysis of Diclofenac sodium by using UV Visible Spectroscopy. The absorption maxima (?max) were found to be 275nm by using Distilled Water as Solvent. The ?max 275nm was used for the whole study. The linearity range was 8-16 µg/ml with a correlation coefficient (r2) of 0.9969. The method was precise and robust with a %RSD less than 2%. The solution was found to be stable up to 4 hours. The proposed method was accurate and specific as per ICH guidelines (Q2).
