Chemical Structure

Lomefloxacin Impurity 9 CAS 183235-15-6 chemical structure

Description

The occurrence of Lomefloxacin Impurity 9 is closely related to a nitrogen-containing heterocyclic scaffold, 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 Lomefloxacin Impurity 9 (CAS 183235-15-6), a pharmacopoeial impurity reference standard (molecular formula C16H19F2N3O, MW 307.34 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Lomefloxacin Impurity 9 (C16H19F2N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Lomefloxacin Impurity 9 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.
