In present work, an effective, innovative enantioselective synthetic strategy for the synthesis of salmeterol xinafoate and its probable process-related impurities was reported. Seven pharmacopeia specified impurities were synthesized and confirmed by FT-IR, mass, 1H & 13C NMR spectroscopy. With respect to the corresponding retention factors, these contaminants were validated using the available RP-HPLC method. These compounds can be used as a reference standard for the active pharmaceutical ingredient manufactures and research organizations.
