Chemical Structure
Description
CATO supplies 2-Bromo-3-chloro-6-fluorobenzaldehyde (CAS 1056264-66-4), a certified reference material (molecular formula C7H3BrClFO, MW 237.45 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system, 2-Bromo-3-chloro-6-fluorobenzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
