Chemical Structure
Description
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.
CATO supplies (E)-[1-(4-Chlorophenyl)-3-(4-methylbenzenesulfonyl)propylidene][(3-fluorophenyl)methoxy]amine (CAS 477867-78-0), a certified reference material (molecular formula C23H21ClFNO3S, MW 445.93 g/mol) for analytical method development and quality control.
Based on its molecular formula C23H21ClFNO3S, (E)-[1-(4-Chlorophenyl)-3-(4-methylbenzenesulfonyl)propylidene][(3-fluorophenyl)methoxy]amine contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 445.93 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
