Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 253.91 g/mol gives 4-Bromo-2,6-dichlorobenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Bromo-2,6-dichlorobenzaldehyde (CAS 111829-72-2), a certified reference material (molecular formula C7H3BrCl2O, MW 253.91 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-2,6-dichlorobenzaldehyde (C7H3BrCl2O) 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 the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
