Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 297.13 g/mol gives 1-Methyl-4-phenylpyridin-1-ium iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Methyl-4-phenylpyridin-1-ium iodide (CAS 36913-39-0), a certified reference material (molecular formula C12H12NI, MW 297.13 g/mol) for analytical method development and quality control.
1-Methyl-4-phenylpyridin-1-ium iodide (C12H12NI) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 1-Methyl-4-phenylpyridin-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.
