Chemical Structure
Description
The occurrence of 2,4-Dibromo-3-(difluoromethyl)pyridine is closely related to a nitrile group, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,4-Dibromo-3-(difluoromethyl)pyridine (CAS 1805252-77-0), a certified reference material (molecular formula C6H3Br2F2N, MW 286.90 g/mol) for analytical method development and quality control.
2,4-Dibromo-3-(difluoromethyl)pyridine (C6H3Br2F2N) 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 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).
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), 2,4-Dibromo-3-(difluoromethyl)pyridine 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.
