Chemical Structure
Description
The molecular framework of 2-(Ethylthio)-6-(furan-2-yl)-4-oxo-1,4-dihydropyrimidine-5-carbonitrile (C11H9N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
CATO supplies 2-(Ethylthio)-6-(furan-2-yl)-4-oxo-1,4-dihydropyrimidine-5-carbonitrile (CAS 156176-72-6), a certified reference material (molecular formula C11H9N3O2S, MW 247.27 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
