Chemical Structure
Description
As a certified reference material (CRM), 8-fluoro-4-methyl-quinoline 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.
8-fluoro-4-methyl-quinoline (CAS 31698-56-3) is a high-purity analytical reference standard with the molecular formula C10H18FN and a molecular weight of 171.26 g/mol.
The molecular framework of 8-fluoro-4-methyl-quinoline (C10H18FN) is characterized by a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
