Chemical Structure
Description
CATO supplies 4-Bromo-2-fluoropyrimidine (CAS 1209458-22-9), a certified reference material (molecular formula C4H2BrFN2, MW 176.97 g/mol) for analytical method development and quality control.
Structurally, 4-Bromo-2-fluoropyrimidine (C4H2BrFN2) contains a nitrile group, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 176.97 g/mol, it falls into the medium-molecular-weight range. 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), 4-Bromo-2-fluoropyrimidine 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.
