Chemical Structure
Description
The occurrence of 2,3,6-Triaminopyridine Dihydrochloride is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,3,6-Triaminopyridine Dihydrochloride (CAS 20284-90-6), a certified reference material (molecular formula C5H8N4HCl, MW 160.60 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, 2,3,6-Triaminopyridine Dihydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 160.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 2,3,6-Triaminopyridine 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.
