Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-(4-Chlorobenzylidene)-6-methyl-2H-thiazolo[3,2-b][1,2,4]triazine-3,7-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-(4-Chlorobenzylidene)-6-methyl-2H-thiazolo[3,2-b][1,2,4]triazine-3,7-dione (CAS 53047-88-4) is a high-purity analytical reference standard with the molecular formula C13H8ClN3O2S and a molecular weight of 305.74 g/mol.
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.
