Description
As a certified reference material (CRM), Voriconazole Impurity 55 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.
Voriconazole Impurity 55 (CAS CATO-C4X-136655) is a certified pharmaceutical impurity reference standard with the molecular formula C16H15F2N5O and a molecular weight of 331.32 g/mol.
The molecular framework of Voriconazole Impurity 55 (C16H15F2N5O) 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 the protonation state of its nitrogen-containing groups, 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.
