Chemical Structure
Description
1-Ethyl-4-methylpyridin-1-ium Bromide (C8H12NBr) contains a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
1-Ethyl-4-methylpyridin-1-ium Bromide (CAS 32353-49-4) is a high-purity analytical reference standard with the molecular formula C8H12NBr and a molecular weight of 202.09 g/mol.
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.
