Description
As a certified reference material (CRM), 6-(Pyridin-3-yl)quinolin-2(1H)-one 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.
6-(Pyridin-3-yl)quinolin-2(1H)-one (CAS 99470-74-3) is a high-purity analytical reference standard with the molecular formula C14H18N6O7S and a molecular weight of 414.39 g/mol.
6-(Pyridin-3-yl)quinolin-2(1H)-one (C14H18N6O7S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.
