Description
Compared with other compounds in its class, the molecular weight of 285.07 g/mol gives 3-(2-Bromoacetyl)-7-fluoro-2H-chromen-2-one, 97% distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(2-Bromoacetyl)-7-fluoro-2H-chromen-2-one, 97% (CAS 1446333-79-4), a certified reference material (molecular formula C11H6BrFO3, MW 285.07 g/mol) for analytical method development and quality control.
3-(2-Bromoacetyl)-7-fluoro-2H-chromen-2-one, 97% (C11H6BrFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-(2-Bromoacetyl)-7-fluoro-2H-chromen-2-one, 97% 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.
