Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Bromo-N-(2,6-difluorophenyl)pyridin-2-amine (CAS 475634-96-9) is a high-purity analytical reference standard with the molecular formula C11H7BrF2N2 and a molecular weight of 285.09 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution, 5-Bromo-N-(2,6-difluorophenyl)pyridin-2-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.09 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).
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.
