Chemical Structure
Description
The molecular framework of N2-Methylpyridine-2,5-diamine dihydrochloride (C6H9N3HCl) is characterized by a nitrile group, chlorine substitution. 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).
N2-Methylpyridine-2,5-diamine dihydrochloride (CAS 1439899-22-5) is a high-purity analytical reference standard with the molecular formula C6H9N3HCl and a molecular weight of 159.62 g/mol.
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), N2-Methylpyridine-2,5-diamine dihydrochloride 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.
