Chemical Structure
Description
The occurrence of 2-(4-(Dimethylamino)styryl)-1-methylpyridin-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.
2-(4-(Dimethylamino)styryl)-1-methylpyridin-1-ium iodide (CAS 2156-29-8) is a high-purity analytical reference standard with the molecular formula C16H19N2I and a molecular weight of 366.24 g/mol.
2-(4-(Dimethylamino)styryl)-1-methylpyridin-1-ium iodide (C16H19N2I) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(4-(Dimethylamino)styryl)-1-methylpyridin-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.
