Chemical Structure

3-((dimethylcarbamoyl)oxy)-1-ethylpyridin-1-ium bromide CAS CATO-C3D-262133 chemical structure

Description

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.

3-((dimethylcarbamoyl)oxy)-1-ethylpyridin-1-ium bromide (CAS CATO-C3D-262133), molecular formula C10H15N2O2Br and molecular weight 275.15 g/mol, is a CATO reference standard with documented purity and traceability.

3-((dimethylcarbamoyl)oxy)-1-ethylpyridin-1-ium bromide (C10H15N2O2Br) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
