Chemical Structure

Moxifloxacin Impurity N41 CAS 172602-81-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 238.59 g/mol gives Moxifloxacin Impurity N41 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Moxifloxacin Impurity N41 (CAS 172602-81-2) is a certified pharmaceutical impurity reference standard with the molecular formula C9H6ClF3O2 and a molecular weight of 238.59 g/mol.

Structurally, Moxifloxacin Impurity N41 (C9H6ClF3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 238.59 g/mol, it falls into the medium-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 Impurity N41 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.
