Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Bromo-1-Fluoro-2-Butanone (CAS 54867-88-8) is a high-purity analytical reference standard with the molecular formula C4H6BrFO and a molecular weight of 168.99 g/mol.
The molecular framework of 1-Bromo-1-Fluoro-2-Butanone (C4H6BrFO) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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.
CATO manufactures 1-Bromo-1-Fluoro-2-Butanone 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.
