Chemical Structure
Description
The occurrence of 2-Bromo-4-fluoro-4'-methyl-1,1'-biphenyl is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-4-fluoro-4'-methyl-1,1'-biphenyl (CAS 2404733-84-0) is a high-purity analytical reference standard with the molecular formula C13H10BrF and a molecular weight of 265.12 g/mol.
Owing to fluorine/bromine substitution, an aromatic ring system, 2-Bromo-4-fluoro-4'-methyl-1,1'-biphenyl is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 265.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-Bromo-4-fluoro-4'-methyl-1,1'-biphenyl 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.
