Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (3Z)-3-[2-Oxo-2-(thiophen-2-yl)ethylidene]piperazin-2-one (CAS 517870-49-4), a certified reference material (molecular formula C10H10N2O2S, MW 222.26 g/mol) for analytical method development and quality control.
(3Z)-3-[2-Oxo-2-(thiophen-2-yl)ethylidene]piperazin-2-one (C10H10N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
As a certified reference material (CRM), (3Z)-3-[2-Oxo-2-(thiophen-2-yl)ethylidene]piperazin-2-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.
