Chemical Structure
Description
The occurrence of 1-Methylpyridin-1-ium-2-carboxylate iodide is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Methylpyridin-1-ium-2-carboxylate iodide (CAS 3785-04-4), a certified reference material (molecular formula C7H7NO2I, MW 264.04 g/mol) for analytical method development and quality control.
The molecular framework of 1-Methylpyridin-1-ium-2-carboxylate iodide (C7H7NO2I) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-Methylpyridin-1-ium-2-carboxylate 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.
