Chemical Structure
Description
3-(3-Bromo-4-fluorophenyl)-3-methylbutan-2-one (CAS 1239964-09-0), molecular formula C11H12BrFO and molecular weight 259.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(3-Bromo-4-fluorophenyl)-3-methylbutan-2-one (C11H12BrFO) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(3-Bromo-4-fluorophenyl)-3-methylbutan-2-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.
