Description
CATO supplies 3-Isobutyl-6-methyl-4-oxo-3,4-dihydrothieno-[3,2-d][1,2,3]triazine-7-carboxylic acid (CAS 1170090-92-2), a certified reference material (molecular formula C11H13N3O3S, MW 267.30 g/mol) for analytical method development and quality control.
3-Isobutyl-6-methyl-4-oxo-3,4-dihydrothieno-[3,2-d][1,2,3]triazine-7-carboxylic acid (C11H13N3O3S) 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.
