6-Chloro-2-(furan-2-yl)-4H-chromen-4-one CAS 7209-73-6

Description

Compared with other compounds in its class, the molecular weight of 246.65 g/mol gives 6-Chloro-2-(furan-2-yl)-4H-chromen-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Chloro-2-(furan-2-yl)-4H-chromen-4-one (CAS 7209-73-6), molecular formula C13H7ClO3 and molecular weight 246.65 g/mol, is a CATO reference standard with documented purity and traceability.

6-Chloro-2-(furan-2-yl)-4H-chromen-4-one (C13H7ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
