Identification and structure elucidation of a new degradation impurity in the multi-component tablets of amlodipine besylate

Popis výsledku v původním jazyce

New unknown impurity at m/z 421.15 was observed during the accelerated stability analysis (40 C/75% relative humidity) in the multi-component tablets of amlodipine besylate by reversed phase ultra-high performance liquid chromatography-mass spectrometry (UHPLC-MS). UHPLC-MS and nuclear magnetic resonance (NMR) techniques were employed to identify and fully characterize the degradation compound. The degradation product was unambiguously identified as 3-ethyl 5-methyl 4(2-chlorophenyl)-6-methyl-2-(morpholin-2-yI)-1,4-dihydropyridine-3,5-dicarboxylate and mechanism of its formation was proposed. It was confirmed that the degradation product was formed by the reaction of amlodipine with formaldehyde originating from the excipients present in the dosage form.
