Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 200.01 g/mol gives 2-Bromo-4-fluorobenzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-4-fluorobenzonitrile (CAS 36282-26-5) is a high-purity analytical reference standard with the molecular formula C7H3BrFN and a molecular weight of 200.01 g/mol.
Owing to a nitrile group, fluorine/bromine substitution, an aromatic ring system, 2-Bromo-4-fluorobenzonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.01 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.
As a certified reference material (CRM), 2-Bromo-4-fluorobenzonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
