Abstract :
A simple, sensitive and economical spectrophotometric method was developed for the determination of Amoxicillin trihydrate in pharmaceutical formulations. This method is based on the formation of pink colored chromogen complex by the reaction of drug with ferric chloride and 1,10-Phenanthroline, which absorbs maximally at 510 nm. Beer’s law is obeyed at a concentration range of 2-20 mcg/ml for method. This method has been successfully applied for the assay of the drug in pharmaceutical formulations.
