Oxytetracycline metabolite (absolute stereochemistry unknown)

α-Apooxytetracycline is a degradation product of oxytetracycline, formed under acidic conditions. After initial dehydration to anhydrooxytetracycline, it 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. α-Apooxytetracycline is an important standard for monitoring oxytetracycline stability.
