Chemical Structure
Description
3-Bromo-4-(trifluoromethyl)benzaldehyde (CAS 372120-55-3) is a high-purity analytical reference standard with the molecular formula C8H4BrF3O and a molecular weight of 253.02 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 3-Bromo-4-(trifluoromethyl)benzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 3-Bromo-4-(trifluoromethyl)benzaldehyde 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.
