Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 263.12 g/mol gives 1-Ethyl-3,4-dimethylpyridin-1-ium iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Ethyl-3,4-dimethylpyridin-1-ium iodide (CAS 6328-84-3), a certified reference material (molecular formula C9H14NI, MW 263.12 g/mol) for analytical method development and quality control.
Structurally, 1-Ethyl-3,4-dimethylpyridin-1-ium iodide (C9H14NI) contains a nitrile group, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 263.12 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.
