Description
As a certified reference material (CRM), 7,8-Difluoro-2-methylquinolin-3-ol 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.
7,8-Difluoro-2-methylquinolin-3-ol (CAS 1314012-50-4), molecular formula C10H7F2NO and molecular weight 195.17 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7,8-Difluoro-2-methylquinolin-3-ol (C10H7F2NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 195.17 g/mol, it falls into the medium-molecular-weight range. 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.
