The occurrence of 4-(4-Hydroxyphenyl)-3-methylbenzo[f]quinolin-4-ium iodide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(4-Hydroxyphenyl)-3-methylbenzo[f]quinolin-4-ium iodide (CAS 5924-24-3), a certified reference material (molecular formula C20H16NOI, MW 413.25 g/mol) for analytical method development and quality control.
4-(4-Hydroxyphenyl)-3-methylbenzo[f]quinolin-4-ium iodide (C20H16NOI) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
