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.
2-(4-Chlorobenzoyl)-3-{[(2-chlorophenyl)sulfanyl]methyl}-1-benzofuran (CAS 338424-02-5), molecular formula C22H14Cl2O2S and molecular weight 413.32 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-(4-Chlorobenzoyl)-3-{[(2-chlorophenyl)sulfanyl]methyl}-1-benzofuran is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 413.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-(4-Chlorobenzoyl)-3-{[(2-chlorophenyl)sulfanyl]methyl}-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.
