harmonization guidelines (ICH) Q1A (R2) to understand the degradation profile of the drug. In the present study, seven degradationproducts were detected by simple mass compatible high performance liquid chromatography (HPLC) and tentatively characterized using high resolution mass spectrometry. Of these, three oxidative degradation (CD1, CD2 & CD3) products were isolated from the reaction mass using preparative
