ALPHA-APO-OXYTETRACYCLINE Usage And Synthesis
Chemical Propertieskhaki-coloured crystalline powder
UsesOxytetracycline metabolite (absolute stereochemistry unknown)
Usesα-Apooxytetracycline is 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. α-apooxytetracycline is an important standard for monitoring oxytetracycline stability.
