Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,6-Dihydro-2H-thiopyran-4-yl trifluoromethanesulfonate.
CATO supplies 3,6-Dihydro-2H-thiopyran-4-yl trifluoromethanesulfonate (CAS 181180-42-7), a certified reference material (molecular formula C6H7F3O3S2, MW 248.24 g/mol) for analytical method development and quality control.
3,6-Dihydro-2H-thiopyran-4-yl trifluoromethanesulfonate (C6H7F3O3S2) contains a sulfone group, 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.
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.
