Chemical Structure
Description
The occurrence of 1-Butyl-4-methylpyridinium iodide is closely related to a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Butyl-4-methylpyridinium iodide (CAS 32353-64-3), molecular formula C10H16NI and molecular weight 277.14 g/mol, is a CATO reference standard with documented purity and traceability.
1-Butyl-4-methylpyridinium iodide (C10H16NI) contains a nitrile group, iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
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.
