Chemical Structure
Description
As a certified reference material (CRM), 3-Fluoro-4,9-dimethoxy-7-methyl-5H-furo[3,2-g]chromen-5-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 3-Fluoro-4,9-dimethoxy-7-methyl-5H-furo[3,2-g]chromen-5-one (CAS 114340-20-4), a certified reference material (molecular formula C14H11FO5, MW 278.23 g/mol) for analytical method development and quality control.
3-Fluoro-4,9-dimethoxy-7-methyl-5H-furo[3,2-g]chromen-5-one (C14H11FO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
