Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 190.01 g/mol gives 5-Bromo-2-fluoro-3-methylpyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-2-fluoro-3-methylpyridine (CAS 29312-98-9), molecular formula C6H5BrFN and molecular weight 190.01 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-2-fluoro-3-methylpyridine (C6H5BrFN) contains a nitrile group, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 5-Bromo-2-fluoro-3-methylpyridine 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.
