N-(3-Chlorophenyl)-2-((3-methyl-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)thio)acetamide (CAS 1058433-56-9) is a high-purity analytical reference standard with the molecular formula C13H11ClN6OS and a molecular weight of 334.78 g/mol.
The molecular framework of N-(3-Chlorophenyl)-2-((3-methyl-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)thio)acetamide (C13H11ClN6OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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.
