Chlortetracycline is the first tetracycline discovered from nature and has been one of the most important antibiotics in human and animal health for over 60 years. Chlortetracycline is a linear tetracycle which can be degraded under various conditions, such as acidity, alkalinity, heat, oxidation, light and temperature. The degradation products are not biologically inert; rather they are oxidative and isomeric analogues with unique physical and chemical properties that are not well characterised. The Chlortetracycline Degradation Set provides the major degradation products described in the literature as a tool for understanding and monitoring the fate of chlortetracycline in biological systems and on storage. | 1.
