Chemical Structure
Description
1,3-Dimethyl-2-(o-tolyl)pyridin-1-ium iodide (CAS 454422-43-6) is a high-purity analytical reference standard with the molecular formula C14H16NI and a molecular weight of 325.19 g/mol.
Structurally, 1,3-Dimethyl-2-(o-tolyl)pyridin-1-ium iodide (C14H16NI) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine 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 325.19 g/mol, it falls into the moderately-high-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.
