Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 312.00 g/mol gives 2,6-Dibromobiphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,6-Dibromobiphenyl (CAS 59080-32-9), molecular formula C12H8Br2 and molecular weight 312.00 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Dibromobiphenyl (C12H8Br2) is characterized by bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
