Description
As a certified reference material (CRM), N’-methylpyridine-3-carboximidamide 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.
N’-methylpyridine-3-carboximidamide dihydrochloride (CAS 856211-98-8) is a high-purity analytical reference standard with the molecular formula C7H9N3HCl and a molecular weight of 171.63 g/mol.
The molecular framework of N’-methylpyridine-3-carboximidamide dihydrochloride (C7H9N3HCl) is characterized by a nitrile group, 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.
