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 3-Ethyl-5-(3-ethylbenzo[d]thiazol-2(3H)-ylidene)-2-thioxooxazolidin-4-one (CAS 36278-87-2), a certified reference material (molecular formula C14H14N2O2S2, MW 306.40 g/mol) for analytical method development and quality control.
3-Ethyl-5-(3-ethylbenzo[d]thiazol-2(3H)-ylidene)-2-thioxooxazolidin-4-one (C14H14N2O2S2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 3-Ethyl-5-(3-ethylbenzo[d]thiazol-2(3H)-ylidene)-2-thioxooxazolidin-4-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.
