Chemical Structure
Description
3,7-Dimethyl-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4(1H)-one (CAS 57250-40-5), molecular formula C6H7N5O and molecular weight 165.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,7-Dimethyl-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4(1H)-one (C6H7N5O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 3,7-Dimethyl-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4(1H)-one 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.
