A simple, sensitive, accurate, precise and economical visible Spectrophotometric method was developed and validated for the estimation of Cilazapril in Bulk form. The method is based on the reaction of Cilazapril with MBTH Reagent [3-Methyl-2-Benzothiazolinone Hydrazone] in the presence of Ferric chloride producing greenish yellow colour chromogen which shows maximum absorbance at 402nm against reagent blank. The Chromogen obeyed Beer's law in the concentration range of 10-50 μg/ml for Cilazapril. The results of the analysis have been validated statistically and recovery studies.

Abstract


A simple, sensitive, accurate, precise and economical visible Spectrophotometric method was developed and validated for the estimation of Cilazapril in Bulk form. The method is based on the reaction of Cilazapril with MBTH Reagent [3-Methyl-2-Benzothiazolinone Hydrazone] in the presence of Ferric chloride producing greenish yellow colour chromogen which shows maximum absorbance at 402nm against reagent blank. The Chromogen obeyed Beer's law in the concentration range of 10-50 μg/ml for Cilazapril. The results of the analysis have been validated statistically and recovery studies.
