Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1,1'-([1,1'-Biphenyl]-4,4'-diyl)bis(2,2-dibromoethan-1-one) (CAS 28179-17-1), a certified reference material (molecular formula C16H10Br4O2, MW 553.87 g/mol) for analytical method development and quality control.
The molecular framework of 1,1'-([1,1'-Biphenyl]-4,4'-diyl)bis(2,2-dibromoethan-1-one) (C16H10Br4O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic 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.
CATO manufactures 1,1'-([1,1'-Biphenyl]-4,4'-diyl)bis(2,2-dibromoethan-1-one) 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.
