6-(4-Bromophenyl)-4-(4-chlorophenyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile CAS 122652-22-6

Description

6-(4-Bromophenyl)-4-(4-chlorophenyl)-2-oxo-1,2-dihydropyridine-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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

6-(4-Bromophenyl)-4-(4-chlorophenyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile (CAS 122652-22-6), molecular formula C18H10BrClN2O and molecular weight 385.64 g/mol, is a CATO reference standard with documented purity and traceability.

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.
