Chemical Structure
Description
2-(2,4-Difluorophenoxy)-4,8-dimethylquinoline (CAS 478032-29-0) is a high-purity analytical reference standard with the molecular formula C17H13F2NO and a molecular weight of 285.29 g/mol.
2-(2,4-Difluorophenoxy)-4,8-dimethylquinoline (C17H13F2NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 2-(2,4-Difluorophenoxy)-4,8-dimethylquinoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
