2-(2-Chlorophenyl)-[1,2,4]triazolo[1,5-a]pyridin-7-amine (CAS 1896545-50-8), molecular formula C12H9ClN4 and molecular weight 244.68 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Chlorophenyl)-[1,2,4]triazolo[1,5-a]pyridin-7-amine (C12H9ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
