Description

Compared with other compounds in its class, the molecular weight of 308.23 g/mol gives 7-Methyl-2-oxo-2H-chromen-4-yl trifluoromethanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-Methyl-2-oxo-2H-chromen-4-yl trifluoromethanesulfonate (CAS 167840-97-3) is a high-purity analytical reference standard with the molecular formula C11H7F3O5S and a molecular weight of 308.23 g/mol.

7-Methyl-2-oxo-2H-chromen-4-yl trifluoromethanesulfonate (C11H7F3O5S) contains a sulfone group, 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
