1-Methyl-2-[(E)-2-(2,3,4-trimethoxyphenyl)ethenyl]pyridin-1-ium iodide CAS 1033847-81-2

Description

CATO supplies 1-Methyl-2-[(E)-2-(2,3,4-trimethoxyphenyl)ethenyl]pyridin-1-ium iodide (CAS 1033847-81-2), a certified reference material (molecular formula C17H20NO3I, MW 413.25 g/mol) for analytical method development and quality control.

The molecular framework of 1-Methyl-2-[(E)-2-(2,3,4-trimethoxyphenyl)ethenyl]pyridin-1-ium iodide (C17H20NO3I) 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 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.

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.
