Chemical Structure
Description
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.
(2Z)-3-(4-Bromophenyl)-3-chloroacrylaldehyde (CAS 161891-32-3) is a high-purity analytical reference standard with the molecular formula C9H6BrClO and a molecular weight of 245.50 g/mol.
(2Z)-3-(4-Bromophenyl)-3-chloroacrylaldehyde (C9H6BrClO) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 (2Z)-3-(4-Bromophenyl)-3-chloroacrylaldehyde 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.
