Enrofloxacin EP Impurity F CAS 131775-99-0

Description

The occurrence of Enrofloxacin EP Impurity F is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Enrofloxacin EP Impurity F (CAS 131775-99-0), a pharmacopoeial impurity reference standard (molecular formula C18H22FN3O, MW 315.39 g/mol) used for the identification and quantification of trace impurities in APIs.

Enrofloxacin EP Impurity F (C18H22FN3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Enrofloxacin EP Impurity F meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
