Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 208.00 g/mol gives 3-Bromo-2-(difluoromethyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-2-(difluoromethyl)pyridine (CAS 1211520-77-2) is a high-purity analytical reference standard with the molecular formula C6H4BrF2N and a molecular weight of 208.00 g/mol.
Owing to a nitrile group, fluorine/bromine substitution, an aromatic ring system, 3-Bromo-2-(difluoromethyl)pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.00 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.
