In the pharmaceutical world, an impurity is considered as any other organic material, besides the drug substance, or ingredients, arise out of synthesis or unwanted chemicals that remains with API’s. Pharmaceuticals impurities are the unwanted chemicals that remain or are generated during the formulation of medicines. The presence and quantity of impurities in pharmaceutical drugs can have a significant impact on their quality and safety, with the continuous pressure for increased industry productivity, there is urgent need for a systematic and comprehensive drug impurity profiling strategy. The impurities present in the drug are adversely affecting the quality of the drug product. There are various types of impurities like starting materials, intermediates, penultimate impurity, by product and degradation product. Impurity profiling helps in detection, identification and quantification of various types of impurities as well as residual solvents in bulk drugs and in pharmaceutical formulations. It is a best way to characterize quality and stability of bulk drugs and pharmaceutical formulations. This review paper deals with the impurity profile of pharmaceuticals.
