Chemical Structure
Description
The occurrence of Methyl 5,6-diaminopyridine-2-carboxylate dihydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyl 5,6-diaminopyridine-2-carboxylate dihydrochloride (CAS 1245643-10-0), a certified reference material (molecular formula C7H9N3O2HCl, MW 203.63 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 5,6-diaminopyridine-2-carboxylate dihydrochloride (C7H9N3O2HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
