Chemical Structure
Description
1-Benzyl-4-bromopyridin-1-ium bromide (CAS 2589-30-2) is a high-purity analytical reference standard with the molecular formula C12H11BrNBr and a molecular weight of 329.04 g/mol.
1-Benzyl-4-bromopyridin-1-ium bromide (C12H11BrNBr) contains a nitrogen-containing heterocyclic scaffold, 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. 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.
