Chemical Structure
Description
2-Amino-7-methoxy-[1,2,4]triazolo[1,5-a]pyridine (CAS 1239648-98-6), molecular formula C7H8N4O and molecular weight 164.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Amino-7-methoxy-[1,2,4]triazolo[1,5-a]pyridine (C7H8N4O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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.
As a certified reference material (CRM), 2-Amino-7-methoxy-[1,2,4]triazolo[1,5-a]pyridine 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.
