Chemical Structure
Description
2-((2,6-Dichlorobenzyl)sulfonyl)-4,5-diphenyl-1-(prop-2-yn-1-yl)-1H-imidazole (CAS 339277-34-8), molecular formula C25H18Cl2N2O2S and molecular weight 481.39 g/mol, is a CATO reference standard with documented purity and traceability.
2-((2,6-Dichlorobenzyl)sulfonyl)-4,5-diphenyl-1-(prop-2-yn-1-yl)-1H-imidazole (C25H18Cl2N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 2-((2,6-Dichlorobenzyl)sulfonyl)-4,5-diphenyl-1-(prop-2-yn-1-yl)-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.
