Chemical Structure
Description
The molecular framework of 4-Bromo-4'-ethoxybiphenyl (C14H13BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. 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.
4-Bromo-4'-ethoxybiphenyl (CAS 58743-80-9), molecular formula C14H13BrO and molecular weight 277.16 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Bromo-4'-ethoxybiphenyl 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.
