2-((4-Amino-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-fluorophenyl)acetamide (CAS 677345-23-2) is a high-purity analytical reference standard with the molecular formula C15H13FN6OS and a molecular weight of 344.37 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 2-((4-Amino-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-fluorophenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
