Chemical Structure
Description
4-[(E)-2-(2,4-Dimethoxyphenyl)ethenyl]-1-ethylpyridin-1-ium iodide (CAS 1025707-57-6) is a high-purity analytical reference standard with the molecular formula C17H20NO2I and a molecular weight of 397.25 g/mol.
The molecular framework of 4-[(E)-2-(2,4-Dimethoxyphenyl)ethenyl]-1-ethylpyridin-1-ium iodide (C17H20NO2I) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
