As a certified reference material (CRM), 3-[(4-Bromobenzenesulfinyl)methyl]-2-(4-chlorobenzoyl)-1-benzofuran meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3-[(4-Bromobenzenesulfinyl)methyl]-2-(4-chlorobenzoyl)-1-benzofuran (CAS 338424-30-9), molecular formula C22H14BrClO3S and molecular weight 473.77 g/mol, is a CATO reference standard with documented purity and traceability.
3-[(4-Bromobenzenesulfinyl)methyl]-2-(4-chlorobenzoyl)-1-benzofuran (C22H14BrClO3S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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.
