Chemical Structure

Ciprofloxacin EP Impurity C HCl(Enrofloxacin EP Impurity G HCl) CAS 528851-31-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ciprofloxacin EP Impurity C HCl(Enrofloxacin EP Impurity G HCl).

As a process- or degradation-related impurity, Ciprofloxacin EP Impurity C HCl(Enrofloxacin EP Impurity G HCl) (CAS 528851-31-2, C15H16FN3O3HCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

The molecular framework of Ciprofloxacin EP Impurity C HCl(Enrofloxacin EP Impurity G HCl) (C15H16FN3O3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Ciprofloxacin EP Impurity C HCl(Enrofloxacin EP Impurity G HCl) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
