Spectrophotometric determination of Ametoctradin and in itscommercial formulations

A simple, precis, rapid sensitive and accurate spectrophoptometric methods have been developed for the estimation of Ametoctradin in pure form and its formulations and spiked vegetables and water samples. This method is based on oxidative coupling of Ametoctradin with MBTH in the presence of Ferric chloride to form green colored product with Maximum of 610 nm. The product obeyed beers law in the concentration range 0. 4 - 2.4 ml (4-24 μgml-1) with molar absorptivity of 0.9917X104. Sandells sensitivity 0.0027777. The assay of results was found to be good agreement with label claim.
