| abstract | The present invention relates to a novel HPLC method for analyzing API formoterol and related substances. In the first method, the mobile phase includes two or more liquids, and the relative concentrations of the liquids change according to a predetermined gradient. In the second method, the mobile phase comprises a first liquid A comprising an aqueous ammonium acetate solution and a second liquid B comprising a dipolar aprotic solvent. In the third method, the mobile phase includes a first liquid A and a second liquid B containing an aqueous ammonium acetate solution having a concentration of 0.001M to 0.025M. The present invention also relates to a method for analyzing a substance comprising detecting and optionally quantifying one or more specific impurities. |
