Abstract :
A simple, sensitive and economical spectrophotometric method was developed for the determination of Emtricitabine in pharmaceutical formulations. This method is based on the separation of colored chloroform layer by the reaction of drug with mordant black 3 , which absorbs maximally at 543 nm. Beer’s law is obeyed at a concentration range of 5-90 mcg/ml for method. This method has been successfully applied for the assay of the drug in pharmaceutical formulations.
