Chemical Structure
Description
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-Butyl-3-(2,4-dichlorophenyl)benzofuran (CAS 204908-15-6) is a high-purity analytical reference standard with the molecular formula C18H16Cl2O and a molecular weight of 319.23 g/mol.
The molecular framework of 2-Butyl-3-(2,4-dichlorophenyl)benzofuran (C18H16Cl2O) is characterized by a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-Butyl-3-(2,4-dichlorophenyl)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.
