CATO supplies 2-Hydroxy-2,6-bis(trifluoromethyl)-2,3-dihydro-4H-pyran-4-one (CAS 933795-21-2), a certified reference material (molecular formula C7H4F6O3, MW 250.10 g/mol) for analytical method development and quality control.
2-Hydroxy-2,6-bis(trifluoromethyl)-2,3-dihydro-4H-pyran-4-one (C7H4F6O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
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.
