6-Cinnamyl-5-methyl-2-(methylthio)-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one (CAS 860786-00-1), molecular formula C16H16N4OS and molecular weight 312.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Cinnamyl-5-methyl-2-(methylthio)-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one (C16H16N4OS) 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 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).
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.
