3,4,5,6-Tetrahydro-1,3-dimethyl-2-[(1-oxido-2-pyridinyl)thio]pyrimidinium tetrafluoroborate (CAS 367252-09-3), molecular formula C11H19N3OSBF4 and molecular weight 328.15 g/mol, is a CATO reference standard with documented purity and traceability.
3,4,5,6-Tetrahydro-1,3-dimethyl-2-[(1-oxido-2-pyridinyl)thio]pyrimidinium tetrafluoroborate (C11H19N3OSBF4) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
