Chemical Structure
Description
CATO supplies (5Z)-3-Methyl-5-{[4-(1H-1,2,4-triazol-1-yl)phenyl]methylidene}-1,3-thiazolidine-2,4-dione (CAS 866008-42-6), a certified reference material (molecular formula C13H10N4O2S, MW 286.31 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (5Z)-3-Methyl-5-{[4-(1H-1,2,4-triazol-1-yl)phenyl]methylidene}-1,3-thiazolidine-2,4-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.31 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).
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.
