Chemical Structure
Description
CATO supplies (E)-2-((4-chlorobenzyl)thio)quinoline-3-carbaldehyde O-(3-chlorobenzoyl) oxime (CAS 551921-75-6), a certified reference material (molecular formula C24H16Cl2N2O2S, MW 467.37 g/mol) for analytical method development and quality control.
(E)-2-((4-chlorobenzyl)thio)quinoline-3-carbaldehyde O-(3-chlorobenzoyl) oxime (C24H16Cl2N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
