Moxifloxacin Impurity 48 HCl CAS 2489671-17-0(Free Base) chemical structure

Description

CATO supplies Moxifloxacin Impurity 48 HCl (CAS 2489671-17-0(Free Base)), a pharmacopoeial impurity reference standard (molecular formula C21H24FN3O5HCl, MW 453.89 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Moxifloxacin Impurity 48 HCl (C21H24FN3O5HCl) contains a flavonoid 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 453.89 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).

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 Moxifloxacin Impurity 48 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.
