Chemical Structure
Description
2-Fluoro-1-methylpyridinium p-toluenesulfonate (CAS 58086-67-2), molecular formula C7H7O3SC6H7FN and molecular weight 283.32 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Fluoro-1-methylpyridinium p-toluenesulfonate (C7H7O3SC6H7FN) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 283.32 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
