2-n-Butyl-4-[(2-bromoethoxy-d4)-3,5-diiodobenzoyl]benzofuran (CAS 1216376-62-3) is a high-purity analytical reference standard with the molecular formula C21H15D4BrI2O3 and a molecular weight of 657.11 g/mol.
The molecular framework of 2-n-Butyl-4-[(2-bromoethoxy-d4)-3,5-diiodobenzoyl]benzofuran (C21H15D4BrI2O3) is characterized by deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, bromine/iodine 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.
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.
As a certified reference material (CRM), 2-n-Butyl-4-[(2-bromoethoxy-d4)-3,5-diiodobenzoyl]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.
