Chemical Structure

(E)-1-ethyl-4-(2,3,4-trimethoxystyryl)pyridin-1-ium iodide CAS 1046808-50-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-1-ethyl-4-(2,3,4-trimethoxystyryl)pyridin-1-ium iodide.

(E)-1-ethyl-4-(2,3,4-trimethoxystyryl)pyridin-1-ium iodide (CAS 1046808-50-7) is a high-purity analytical reference standard with the molecular formula C18H22NO3I and a molecular weight of 427.28 g/mol.

The molecular framework of (E)-1-ethyl-4-(2,3,4-trimethoxystyryl)pyridin-1-ium iodide (C18H22NO3I) 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 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).

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.

As a certified reference material (CRM), (E)-1-ethyl-4-(2,3,4-trimethoxystyryl)pyridin-1-ium iodide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
