N-([1,3]Dioxolo[4',5':4,5]benzo[1,2-d]thiazol-6-yl)-5,6-dihydro-1,4-dioxine-2-carboxamide (CAS 892853-67-7), molecular formula C13H10N2O5S and molecular weight 306.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-([1,3]Dioxolo[4',5':4,5]benzo[1,2-d]thiazol-6-yl)-5,6-dihydro-1,4-dioxine-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
