3-Ethyl-6-fluoro-3-methyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one CAS 918645-97-3

Description

Compared with other compounds in its class, the molecular weight of 334.39 g/mol gives 3-Ethyl-6-fluoro-3-methyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Ethyl-6-fluoro-3-methyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one (CAS 918645-97-3), molecular formula C21H19FN2O and molecular weight 334.39 g/mol, is a CATO reference standard with documented purity and traceability.

3-Ethyl-6-fluoro-3-methyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one (C21H19FN2O) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 3-Ethyl-6-fluoro-3-methyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one 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.
