Chemical Structure
Description
The occurrence of 1-Methyl-[4,4']bipyridinyl-1-ium; iodide is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Methyl-[4,4']bipyridinyl-1-ium; iodide (CAS 79762-56-4) is a high-purity analytical reference standard with the molecular formula C11H11N2I and a molecular weight of 298.12 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution, 1-Methyl-[4,4']bipyridinyl-1-ium; iodide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 1-Methyl-[4,4']bipyridinyl-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.
