Chemical Structure
Description
The occurrence of N-CYano-4-methoxypyridinium tetrafluoroborate is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-CYano-4-methoxypyridinium tetrafluoroborate (CAS 1229618-90-9), molecular formula C7H7N2OBF4 and molecular weight 221.95 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-CYano-4-methoxypyridinium tetrafluoroborate (C7H7N2OBF4) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 221.95 g/mol, it falls into the medium-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.
