Chemical Structure
Description
(Z)-3-bromo-4-(4-chlorophenyl)but-3-en-2-one (CAS 634906-83-5), molecular formula C10H8BrClO and molecular weight 259.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (Z)-3-bromo-4-(4-chlorophenyl)but-3-en-2-one (C10H8BrClO) is characterized by a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring 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).
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.
CATO manufactures (Z)-3-bromo-4-(4-chlorophenyl)but-3-en-2-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.
