Chemical Structure
Description
(E)-1-(4-Bromophenyl)-3-(4-chlorophenyl)prop-2-en-1-one (CAS 126443-16-1), molecular formula C15H10BrClO and molecular weight 321.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-1-(4-Bromophenyl)-3-(4-chlorophenyl)prop-2-en-1-one (C15H10BrClO) is characterized by a hydroxyl group, an ether linkage, chlorine/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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (E)-1-(4-Bromophenyl)-3-(4-chlorophenyl)prop-2-en-1-one 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.
