As a certified reference material (CRM), 6-Chlorofuro[2,3-b]pyridin-3(2H)-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-Chlorofuro[2,3-b]pyridin-3(2H)-one (CAS 1196146-87-8) is a high-purity analytical reference standard with the molecular formula C7H4ClNO2 and a molecular weight of 169.57 g/mol.
The molecular framework of 6-Chlorofuro[2,3-b]pyridin-3(2H)-one (C7H4ClNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
