Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

[1,2,4]Thiadiazino[3,4-b]benzothiazole-8-carboxylic acid, 3,4-dihydro-, 2,2-dioxide (CAS 301308-77-0) is a high-purity analytical reference standard with the molecular formula C10H8N2O4S2 and a molecular weight of 284.31 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, [1,2,4]Thiadiazino[3,4-b]benzothiazole-8-carboxylic acid, 3,4-dihydro-, 2,2-dioxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
