7-Hydroxy-3-(naphthalen-1-yl)-2-(trifluoromethyl)-4H-chromen-4-one CAS 307544-91-8

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

7-Hydroxy-3-(naphthalen-1-yl)-2-(trifluoromethyl)-4H-chromen-4-one (CAS 307544-91-8), molecular formula C20H11F3O3 and molecular weight 356.29 g/mol, is a CATO reference standard with documented purity and traceability.

7-Hydroxy-3-(naphthalen-1-yl)-2-(trifluoromethyl)-4H-chromen-4-one (C20H11F3O3) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 7-Hydroxy-3-(naphthalen-1-yl)-2-(trifluoromethyl)-4H-chromen-4-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.
