Safety of the drug molecule is dependent on the various impurities formed during chemical transformation which may cause drug product instability, decreased product performance, loss in potency, and/or formation of potentially genotoxic impurities. Therefore, it is essential to identify and quantify the impurities generated during the drug development stage. Herein, we describe the synthesis and characterization of Impurity D of Metoprolol, 3-[4-(2-methoxyethyl)phenoxy]propane-1,2-diol (1), reported in European Pharmacopeia. The synthesis of impurity D has been accomplished in two steps; starting from Epichlorhydrin under three different set of conditions.
