Chemical Structure

5-Fluoro-7-hydroxy-2H-chromene-3-carbaldehyde CAS 1228581-47-2 chemical structure

Description

5-Fluoro-7-hydroxy-2H-chromene-3-carbaldehyde (CAS 1228581-47-2) is a high-purity analytical reference standard with the molecular formula C10H7FO3 and a molecular weight of 194.16 g/mol.

5-Fluoro-7-hydroxy-2H-chromene-3-carbaldehyde (C10H7FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. 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.

As a certified reference material (CRM), 5-Fluoro-7-hydroxy-2H-chromene-3-carbaldehyde 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.
