Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Potassium (3-bromo-5-methoxyphenyl)trifluoroborate (CAS 1189097-39-9), a certified reference material (molecular formula C7H6BBrF3OK, MW 292.93 g/mol) for analytical method development and quality control.
Owing to a salt form, a hydroxyl group, an ether linkage, fluorine/bromine substitution, Potassium (3-bromo-5-methoxyphenyl)trifluoroborate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.93 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.
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.
