Chemical Structure
Description
The occurrence of Moxifloxacin EP Impurity A HCl is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Moxifloxacin EP Impurity A HCl (CAS 151282-23-4) is a certified pharmaceutical impurity reference standard with the molecular formula C20H21F2N3O3HCl and a molecular weight of 425.86 g/mol.
Structurally, Moxifloxacin EP Impurity A HCl (C20H21F2N3O3HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 425.86 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures Moxifloxacin EP Impurity A 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.
