Abstract
The aim of present work is to find out a simple, specific, colorimetric / spectrophotometric method developed for the detection of different pharmaceutical dosage forms using analytical and chemical reagents in bulk and pharmaceutical formulation. The developed methods have been stastically validated for application in pharmaceutical quality control laboratory. The proposed method was ascertained by actual determination of fixed concentration of the drug with in Beers range and finding out the absorbance by the proposed method with suitable reagent. Hence in present work different reagents, their properties, uses, mechanism of action and applications are enlisted.
