4,4'-(Ethene-1,2-diyl)bis(1-methylpyridin-1-ium) CAS 41491-90-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4'-(Ethene-1,2-diyl)bis(1-methylpyridin-1-ium).

4,4'-(Ethene-1,2-diyl)bis(1-methylpyridin-1-ium) (CAS 41491-90-1), molecular formula C14H16N2 and molecular weight 212.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4'-(Ethene-1,2-diyl)bis(1-methylpyridin-1-ium) (C14H16N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 4,4'-(Ethene-1,2-diyl)bis(1-methylpyridin-1-ium) 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.
