Eravacycline — impurities and related standards
All 7 Eravacycline-related compounds in the CATO catalogue, listed with their CAS numbers, molecular formulae and stock status. If the compound you need is not listed, send the structure or the impurity designation and we will check whether it can be synthesised or isolated.
Eravacycline is a synthetic fluorocycline antibacterial of the tetracycline class, developed for parenteral use against complicated intra-abdominal infections and active against several tetracycline-resistant Gram-negative organisms. Its structure carries a fluorinated tetracycline core with additional substituents, so its impurity profile reflects a multi-step synthesis: partially fluorinated intermediates, epimers at the core stereocentres, and hydrolytic or oxidative degradation products formed under aqueous conditions. The standards gathered on this page are non-compendial eravacycline impurities, many carrying the TP-series development codes, provided as individual characterised lots for process-impurity identification, stability-indicating method development and peak assignment in related-substance testing.
