Levofloxacin impurity 02 CAS 3403-82-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 162.23 g/mol gives Levofloxacin impurity 02 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Levofloxacin impurity 02 (CAS 3403-82-5) is a certified pharmaceutical impurity reference standard with the molecular formula C8H18O3 and a molecular weight of 162.23 g/mol.

Levofloxacin impurity 02 (C8H18O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.

As a certified reference material (CRM), Levofloxacin impurity 02 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
