Chemical Structure
Description
4-Bromo-3-(trifluoromethyl)benzaldehyde (CAS 34328-47-7), molecular formula C8H4BrF3O and molecular weight 253.02 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-3-(trifluoromethyl)benzaldehyde (C8H4BrF3O) contains a hydroxyl group, an ether linkage, fluorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4-Bromo-3-(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.
