Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,6-Dihydro-2H-pyran-3-yl trifluoromethanesulfonate.
CATO supplies 5,6-Dihydro-2H-pyran-3-yl trifluoromethanesulfonate (CAS 1227068-80-5), a certified reference material (molecular formula C6H7F3O4S, MW 232.18 g/mol) for analytical method development and quality control.
5,6-Dihydro-2H-pyran-3-yl trifluoromethanesulfonate (C6H7F3O4S) 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.
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.
