Chemical Structure
Description
The occurrence of 4-Bromo-6-fluoropyridin-3-amine hydrobromide is closely related to a nitrile group, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-6-fluoropyridin-3-amine hydrobromide (CAS 2411641-52-4) is a high-purity analytical reference standard with the molecular formula C5H4BrFN2HBr and a molecular weight of 271.91 g/mol.
Owing to a nitrile group, fluorine/bromine substitution, 4-Bromo-6-fluoropyridin-3-amine hydrobromide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.91 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.
