Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,4'-Bis(bromomethyl)-1,1'-biphenyl (CAS 20248-86-6) is a high-purity analytical reference standard with the molecular formula C14H12Br2 and a molecular weight of 340.05 g/mol.
The molecular framework of 4,4'-Bis(bromomethyl)-1,1'-biphenyl (C14H12Br2) is characterized by 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 4,4'-Bis(bromomethyl)-1,1'-biphenyl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
