Chemical Structure
Description
The molecular framework of 1,4-Bis(4-bromophenyl)-1,4-butanedione (C16H12Br2O2) is characterized by a carboxylic acid group, 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. 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).
1,4-Bis(4-bromophenyl)-1,4-butanedione (CAS 2461-83-8), molecular formula C16H12Br2O2 and molecular weight 396.07 g/mol, is a CATO reference standard with documented purity and traceability.
