Description
CATO manufactures 4'-Bromo-3-fluoro-1,1'-biphenyl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4'-Bromo-3-fluoro-1,1'-biphenyl (CAS 40641-65-4) is a high-purity analytical reference standard with the molecular formula C12H8BrF and a molecular weight of 251.09 g/mol.
Owing to fluorine/bromine substitution, an aromatic ring system, 4'-Bromo-3-fluoro-1,1'-biphenyl is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 251.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
