“…It is well established that conduction band electrons (e − ) and valence band holes (h + ) are generated when an aqueous Ornidazole epoxide represents one of the degradation intermediates that previous studies on showed [22,36]. The scission of the C C bond in ornidazole epoxide may lead to the formation of 1,2-dimethyl-5-nitroimidazole (Compound II, t R = 0.95 min, m/z = 142).…”

“…According to the literature, metronidazole loses its nitroimidazole structure in alkaline media [35]. Furthermore, the alkaline hydrolysis of clarithromycin was reported in the literature but the reaction mechanism was not proposed [36]. Therefore, the following experiments were done without pH adjustment.…”

“…In the publication [19], it has been shown that ornidazole is prone to degradation under stress conditions: impurities are formed during the oxidation of ornidazole, under extreme pH values, and as a result of photodegradation [20]. In the work [21], it is shown that injection drugs of ornidazole contain the impurity identified as ornidazole-diol in large quantities.…”
