Chemical Structure
Description
3-(Phenylsulfonyl)-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4-amine (CAS 1338218-79-3), molecular formula C10H8N6O2S and molecular weight 276.27 g/mol, is a CATO reference standard with documented purity and traceability.
3-(Phenylsulfonyl)-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4-amine (C10H8N6O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
