| Oxytetracycline EP Impurity E | A degradation product of oxytetracycline formed under acidic conditions. An initial dehydration to anhydrooxytetracycline then undergoes an internal cyclisation of the C5-OH to the C12 ketone. The resulting cleavage of the C12-C12a bond generates two isomers, α- and β-apooxytetracycline. beta-Apooxytetracycline is an important standard for monitoring oxytetracycline stability.
