Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Allyl-2-((3,4-dichlorobenzyl)sulfonyl)-4,5-diphenyl-1H-imidazole.
1-Allyl-2-((3,4-dichlorobenzyl)sulfonyl)-4,5-diphenyl-1H-imidazole (CAS 866017-33-6), molecular formula C25H20Cl2N2O2S and molecular weight 483.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Allyl-2-((3,4-dichlorobenzyl)sulfonyl)-4,5-diphenyl-1H-imidazole (C25H20Cl2N2O2S) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 manufactures 1-Allyl-2-((3,4-dichlorobenzyl)sulfonyl)-4,5-diphenyl-1H-imidazole 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.
