Abstract

A NEW COLORIMETRIC DEVELOPMENT AND VALIDATION OF VISIBLE METHOD FOR ESTIMATION OF NAPROXEN IN BULK FORMULATION

Ch. Sai Manoj* and VVS. Rajendra Prasad

ABSTRACT

A simple, sensitive, accurate, precise and economical visible Spectrophotometric method was developed and validated for the estimation of Naproxen in Bulk form. The method is based on the reaction of Naproxen with MBTH Reagent [3-Methyl-2-Benzothiazolinone Hydrazone] in the presence of ferric chloride giving greenish blue colour chromogen which shows maximum absorbance at 580nm against reagent blank. The Chromogen obeyed Beer’s law in the concentration range of 10-50 μg/ml for Naproxen. The results of the analysis have been validated statistically and recovery studies.

Keywords: Naproxen, MBTH Reagent [3-Methyl-2-Benzothiazolinone Hydrazone], Ferric chloride, Visible Spectrophotometric.
