6-(3-Bromophenyl)-4-(4-chlorophenyl)-2-hydroxypyridine-3-carbonitrile CAS 478261-45-9

Description

Compared with other compounds in its class, the molecular weight of 385.64 g/mol gives 6-(3-Bromophenyl)-4-(4-chlorophenyl)-2-hydroxypyridine-3-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 6-(3-Bromophenyl)-4-(4-chlorophenyl)-2-hydroxypyridine-3-carbonitrile (CAS 478261-45-9), a certified reference material (molecular formula C18H10BrClN2O, MW 385.64 g/mol) for analytical method development and quality control.

6-(3-Bromophenyl)-4-(4-chlorophenyl)-2-hydroxypyridine-3-carbonitrile (C18H10BrClN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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.

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.
