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.
CATO supplies 2-[(E)-2-(2,4-Dimethoxyphenyl)ethenyl]-1-hexylpyridin-1-ium iodide (CAS 1047974-83-3), a certified reference material (molecular formula C21H28NO2I, MW 453.36 g/mol) for analytical method development and quality control.
Structurally, 2-[(E)-2-(2,4-Dimethoxyphenyl)ethenyl]-1-hexylpyridin-1-ium iodide (C21H28NO2I) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 453.36 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
