Description
Tetracycline is a broad-spectrum antibacterial and selection agent. 4-Epitetracycline ammonium salt is a salt form of 4-epitetracycline, a derivative of the antibiotic tetracycline. It is produced when tetracycline undergoes an epimerization. Under acid conditions, tetracycline undergoes a reversible epimerization at the fourth carbon, producing a mixture of tetracycline and 4-Epitetracycline. 4-Epitetracycline is a metabolite/impurity derived from the degradation of tetracycline and has been shown to display reduced antibiotic activity. This product can be used as analytical reference compound.
