Chemical Structure
Description
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.
1-[(4-Bromophenyl)methyl]-2-(2-ethoxy-2-oxoethyl)pyridin-1-ium bromide (CAS 477710-22-8) is a high-purity analytical reference standard with the molecular formula C16H17BrNO2Br and a molecular weight of 415.12 g/mol.
1-[(4-Bromophenyl)methyl]-2-(2-ethoxy-2-oxoethyl)pyridin-1-ium bromide (C16H17BrNO2Br) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
