Description
As a certified reference material (CRM), 5-(3-Bromobenzylidene)-2-(4-propoxyphenyl)thiazolo[3,2-b][1,2,4]triazol-6(5H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 5-(3-Bromobenzylidene)-2-(4-propoxyphenyl)thiazolo[3,2-b][1,2,4]triazol-6(5H)-one (CAS 618076-54-3), a certified reference material (molecular formula C20H16BrN3O2S, MW 442.33 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 5-(3-Bromobenzylidene)-2-(4-propoxyphenyl)thiazolo[3,2-b][1,2,4]triazol-6(5H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 442.33 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.
