What is Spectrophotometric Analysis of Aspirin about?

This document describes a spectrophotometric method for determining the aspirin content in pharmaceutical formulations. The method relies on the oxidation-reduction reaction between aspirin and potassium permanganate to form a violet-colored complex. Tablet samples from three manufacturers were analyzed using a spectrophotometer to measure absorbance of the complex at 350 nm. A calibration curve was used to calculate the aspirin concentration in each sample. The results were compared to assess the precision
