Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 191.00 g/mol gives 2-Bromo-3-fluorophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-3-fluorophenol (CAS 443-81-2), molecular formula C6H4BrFO and molecular weight 191.00 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-3-fluorophenol (C6H4BrFO) 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. 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.
CATO manufactures 2-Bromo-3-fluorophenol 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.
