(2E)-3-(2-{[(4-chlorophenyl)methyl]sulfanyl}quinolin-3-yl)-1-(4-methoxyphenyl)prop-2-en-1-one CAS 478065-20-2

Description

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.

(2E)-3-(2-{[(4-chlorophenyl)methyl]sulfanyl}quinolin-3-yl)-1-(4-methoxyphenyl)prop-2-en-1-one (CAS 478065-20-2), molecular formula C26H20ClNO2S and molecular weight 445.96 g/mol, is a CATO reference standard with documented purity and traceability.

(2E)-3-(2-{[(4-chlorophenyl)methyl]sulfanyl}quinolin-3-yl)-1-(4-methoxyphenyl)prop-2-en-1-one (C26H20ClNO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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.
