CATO supplies Nemonoxacin-13C,d3 (CAS CATO-C4X-312862), a certified reference material (molecular formula C19[13C]H22D3N3O4, MW 375.44 g/mol) for analytical method development and quality control.
The molecular framework of Nemonoxacin-13C,d3 (C19[13C]H22D3N3O4) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Nemonoxacin-13C,d3 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.
