1-Fluoropyridin-1-ium-2-sulfonate (CAS 130409-71-1), molecular formula C5H4FNO3S and molecular weight 177.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Fluoropyridin-1-ium-2-sulfonate (C5H4FNO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 177.15 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).
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.
