Chemical Structure

3-Bromo-2-(1,1-difluoroethyl)-5-fluoropyridine CAS 2573798-19-1 chemical structure

Description

The occurrence of 3-Bromo-2-(1,1-difluoroethyl)-5-fluoropyridine 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.

3-Bromo-2-(1,1-difluoroethyl)-5-fluoropyridine (CAS 2573798-19-1), molecular formula C7H5BrF3N and molecular weight 240.02 g/mol, is a CATO reference standard with documented purity and traceability.

3-Bromo-2-(1,1-difluoroethyl)-5-fluoropyridine (C7H5BrF3N) 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), 3-Bromo-2-(1,1-difluoroethyl)-5-fluoropyridine 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.
