Chemical Structure
Description
As a certified reference material (CRM), 2-(4-Chlorophenyl)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.
CATO supplies 2-(4-Chlorophenyl)benzofuran (CAS 39195-66-9), a certified reference material (molecular formula C14H9ClO, MW 228.67 g/mol) for analytical method development and quality control.
Structurally, 2-(4-Chlorophenyl)benzofuran (C14H9ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 228.67 g/mol, it falls into the medium-molecular-weight range. 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.
