Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 340.01 g/mol gives (2-Bromophenyl)(4-bromophenyl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2-Bromophenyl)(4-bromophenyl)methanone (CAS 78281-59-1), molecular formula C13H8Br2O and molecular weight 340.01 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2-Bromophenyl)(4-bromophenyl)methanone (C13H8Br2O) is characterized by a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (2-Bromophenyl)(4-bromophenyl)methanone 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.
