Chemical Structure
Description
5-Fluoro-2-oxo-1,2-dihydropyridine-3-carbonitrile (CAS 1506013-17-7), molecular formula C6H3FN2O and molecular weight 138.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Fluoro-2-oxo-1,2-dihydropyridine-3-carbonitrile (C6H3FN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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 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), 5-Fluoro-2-oxo-1,2-dihydropyridine-3-carbonitrile 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.
