Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 394.34 g/mol gives 4-Chloro-6-methoxy-2-phenylquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chloro-6-methoxy-2-phenylquinoline (CAS 50593-72-1), molecular formula C20H24ClN3OHCl and molecular weight 394.34 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-6-methoxy-2-phenylquinoline (C20H24ClN3OHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
