CATO supplies 10-(4-Chlorophenyl)-7-[(E)-2-phenylethenyl]-4-thia-6,10-diazatricyclo[6.3.0.0^{2,6}]undecane-9,11-dione (CAS 321522-01-4), a certified reference material (molecular formula C22H19ClN2O2S, MW 410.92 g/mol) for analytical method development and quality control.
The molecular framework of 10-(4-Chlorophenyl)-7-[(E)-2-phenylethenyl]-4-thia-6,10-diazatricyclo[6.3.0.0^{2,6}]undecane-9,11-dione (C22H19ClN2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
