Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 249.05 g/mol gives 4-Formyl-1-methylpyridin-1-ium iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Formyl-1-methylpyridin-1-ium iodide (CAS 13441-53-7), a certified reference material (molecular formula IC7H8NO, MW 249.05 g/mol) for analytical method development and quality control.
4-Formyl-1-methylpyridin-1-ium iodide (IC7H8NO) contains an amide group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
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.
CATO manufactures 4-Formyl-1-methylpyridin-1-ium iodide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
