Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 230.15 g/mol gives 1-Butyl-3-methylpyridin-1-ium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Butyl-3-methylpyridin-1-ium bromide (CAS 26576-85-2) is a high-purity analytical reference standard with the molecular formula C10H16NBr and a molecular weight of 230.15 g/mol.
1-Butyl-3-methylpyridin-1-ium bromide (C10H16NBr) contains a nitrile group, bromine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
