Description
CATO supplies 5'-Fluoro-2'-hydroxychalcone (CAS 1431-92-1), a certified reference material (molecular formula C15H11FO2, MW 242.25 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, 5'-Fluoro-2'-hydroxychalcone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 5'-Fluoro-2'-hydroxychalcone 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.
