Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 208.99 g/mol gives 3-Bromo-4,5-difluorophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-4,5-difluorophenol (CAS 1807120-34-8) is a high-purity analytical reference standard with the molecular formula C6H3BrF2O and a molecular weight of 208.99 g/mol.
The molecular framework of 3-Bromo-4,5-difluorophenol (C6H3BrF2O) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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 3-Bromo-4,5-difluorophenol 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.
