Description
CATO manufactures 3,3＇,4,4＇-Tetrabromobiphenyl 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.
3,3＇,4,4＇-Tetrabromobiphenyl (CAS 77102-82-0) is a high-purity analytical reference standard with the molecular formula C12H6Br4 and a molecular weight of 469.79 g/mol.
Owing to bromine substitution, an aromatic ring system, 3,3＇,4,4＇-Tetrabromobiphenyl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 469.79 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
