Chemical Structure
Description
4-Bromo-2-fluorobiphenyl (CAS 41604-19-7), molecular formula C12H8BrF and molecular weight 251.09 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Bromo-2-fluorobiphenyl (C12H8BrF) contains fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 251.09 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-fluorobiphenyl 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.
