Chemical Structure
Description
Owing to deuterium isotope labeling, bromine substitution, an aromatic ring system, 4,4′-Dibromobiphenyl-d8 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4,4′-Dibromobiphenyl-d8 (CAS 80523-79-1) is a high-purity analytical reference standard with the molecular formula C12D8Br2 and a molecular weight of 320.05 g/mol.
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.
CATO manufactures 4,4′-Dibromobiphenyl-d8 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.
