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-(1-ethylpyridin-2(1H)-ylidene)-2-thioxooxazolidin-4-one (CAS 93072-23-2), a certified reference material (molecular formula C12H14N2O2S, MW 250.32 g/mol) for analytical method development and quality control.
3-Ethyl-5-(1-ethylpyridin-2(1H)-ylidene)-2-thioxooxazolidin-4-one (C12H14N2O2S) 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.
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.
