A Colorimetric Assay Method For Nabumetone
A simple spectrophotometric method has been developed for the estimation of nabumetone in pure and pharmaceutical dosage forms. In this method, the drug is made to react with ferric chlorideand 1,10-phenanthroline when a red complex is formed. The chromogen can be estimated at 517 nm against a reagent blank. The method obeys Beer's law in the concentration range of 1-5Î¼g/ml of the drug.
