Chemical Structure
Description
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.
6-(Phenylamino)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (CAS 98421-02-4), molecular formula C10H9N3OS and molecular weight 219.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-(Phenylamino)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (C10H9N3OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
