Chemical Structure
Description
CATO supplies 2,6-Di-tert-butylpyrylium trifluoromethanesulfonate (CAS 125455-66-5), a certified reference material (molecular formula C13H21OCF3O3S, MW 342.37 g/mol) for analytical method development and quality control.
Structurally, 2,6-Di-tert-butylpyrylium trifluoromethanesulfonate (C13H21OCF3O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 342.37 g/mol, it falls into the moderately-high-molecular-weight range. 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.
