Chemical Structure
Description
The occurrence of 2-fluoro-1-methylpyridin-1-ium trifluoromethanesulfonate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-fluoro-1-methylpyridin-1-ium trifluoromethanesulfonate (CAS 921754-29-2), molecular formula CF3O3SC6H7FN and molecular weight 261.19 g/mol, is a CATO reference standard with documented purity and traceability.
2-fluoro-1-methylpyridin-1-ium trifluoromethanesulfonate (CF3O3SC6H7FN) contains an amide group, 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. 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.
CATO manufactures 2-fluoro-1-methylpyridin-1-ium trifluoromethanesulfonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
