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 1,1-Bis(4-chlorophenyl)-2-(2,6-dichlorobenzenesulfonyl)ethan-1-ol (CAS 337919-96-7), a certified reference material (molecular formula C20H14Cl4O3S, MW 476.20 g/mol) for analytical method development and quality control.
The molecular framework of 1,1-Bis(4-chlorophenyl)-2-(2,6-dichlorobenzenesulfonyl)ethan-1-ol (C20H14Cl4O3S) is characterized by a steroid core, 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.
CATO manufactures 1,1-Bis(4-chlorophenyl)-2-(2,6-dichlorobenzenesulfonyl)ethan-1-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
