Chemical Structure
Description
The occurrence of 4-[bromo(phenyl)methyl]-1,2-difluorobenzene is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-[bromo(phenyl)methyl]-1,2-difluorobenzene (CAS 1248278-90-1), a certified reference material (molecular formula C13H9BrF2, MW 283.11 g/mol) for analytical method development and quality control.
The molecular framework of 4-[bromo(phenyl)methyl]-1,2-difluorobenzene (C13H9BrF2) is characterized by fluorine/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 4-[bromo(phenyl)methyl]-1,2-difluorobenzene 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.
