Chemical Structure
Description
CATO supplies Naphthalen-2-yl 2-(4-bromophenyl)quinoline-4-carboxylate (CAS 355433-81-7), a certified reference material (molecular formula C26H16BrNO2, MW 454.31 g/mol) for analytical method development and quality control.
Naphthalen-2-yl 2-(4-bromophenyl)quinoline-4-carboxylate (C26H16BrNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
