Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, 4-[(E)-2-(2,3-Dimethoxyphenyl)ethenyl]-1-ethylpyridin-1-ium iodide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 397.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 4-[(E)-2-(2,3-Dimethoxyphenyl)ethenyl]-1-ethylpyridin-1-ium iodide (CAS 1046808-44-9), a certified reference material (molecular formula C17H20NO2I, MW 397.25 g/mol) for analytical method development and quality control.
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.
