CATO supplies (E)-3-(3-Oxoprop-1-en-1-yl)-7,8-dihydro-6H-indeno[5,6-e][1,2,4]triazine 1-oxide (CAS 1956426-87-1), a certified reference material (molecular formula C13H11N3O2, MW 241.25 g/mol) for analytical method development and quality control.
(E)-3-(3-Oxoprop-1-en-1-yl)-7,8-dihydro-6H-indeno[5,6-e][1,2,4]triazine 1-oxide (C13H11N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
