Chemical Structure
Description
The molecular framework of N-Nitroso-N-Desmethyl Levofloxacin-d8 (C17H9D8FN4O5) is characterized by deuterium isotope labeling, a flavonoid core, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
N-Nitroso-N-Desmethyl Levofloxacin-d8 (CAS CATO-C4X-218725) is a high-purity analytical reference standard with the molecular formula C17H9D8FN4O5 and a molecular weight of 384.39 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), N-Nitroso-N-Desmethyl Levofloxacin-d8 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.
