Description
CATO manufactures 3,4',5-Tribromo-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.
3,4',5-Tribromo-1,1'-biphenyl (CAS 72416-87-6) is a high-purity analytical reference standard with the molecular formula C12H7Br3 and a molecular weight of 390.90 g/mol.
The molecular framework of 3,4',5-Tribromo-1,1'-biphenyl (C12H7Br3) 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.
