Chemical Structure

1-Methyl-4-(pyridin-1-ium-1-ylmethyl)pyridin-1-ium iodide CAS 64169-89-7 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 1-Methyl-4-(pyridin-1-ium-1-ylmethyl)pyridin-1-ium iodide.

1-Methyl-4-(pyridin-1-ium-1-ylmethyl)pyridin-1-ium iodide (CAS 64169-89-7) is a high-purity analytical reference standard with the molecular formula C12H14N2I and a molecular weight of 313.16 g/mol.

The molecular framework of 1-Methyl-4-(pyridin-1-ium-1-ylmethyl)pyridin-1-ium iodide (C12H14N2I) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.

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-Methyl-4-(pyridin-1-ium-1-ylmethyl)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.
