Chemical Structure
Description
CATO supplies 6-(4-Chlorophenyl)-5-[(E)-2-nitroethenyl]imidazo[2,1-b][1,3]thiazole (CAS 338404-62-9), a certified reference material (molecular formula C13H8ClN3O2S, MW 305.74 g/mol) for analytical method development and quality control.
6-(4-Chlorophenyl)-5-[(E)-2-nitroethenyl]imidazo[2,1-b][1,3]thiazole (C13H8ClN3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 6-(4-Chlorophenyl)-5-[(E)-2-nitroethenyl]imidazo[2,1-b][1,3]thiazole 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.
