1-Ethyl-2-[(1E)-(1-ethyl-2(1H)-quinolinylidene)methyl]quinolinium CAS 64496-43-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 327.44 g/mol gives 1-Ethyl-2-[(1E)-(1-ethyl-2(1H)-quinolinylidene)methyl]quinolinium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Ethyl-2-[(1E)-(1-ethyl-2(1H)-quinolinylidene)methyl]quinolinium (CAS 64496-43-1) is a high-purity analytical reference standard with the molecular formula C23H23N2 and a molecular weight of 327.44 g/mol.

The molecular framework of 1-Ethyl-2-[(1E)-(1-ethyl-2(1H)-quinolinylidene)methyl]quinolinium (C23H23N2) 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), 1-Ethyl-2-[(1E)-(1-ethyl-2(1H)-quinolinylidene)methyl]quinolinium 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.
