Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-(4-Bromophenyl)benzofuran-3-carboxylate.
Ethyl 2-(4-Bromophenyl)benzofuran-3-carboxylate (CAS 1423700-57-5), molecular formula C17H13BrO3 and molecular weight 345.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-(4-Bromophenyl)benzofuran-3-carboxylate (C17H13BrO3) is characterized by a steroid core, a hydroxyl group, an ether linkage, bromine 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), Ethyl 2-(4-Bromophenyl)benzofuran-3-carboxylate 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.
