Chemical Structure
Description
N-(2,5-difluorobenzyl)-2-(1H-1,2,4-triazol-1-yl)acetamide (C11H10F2N4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
N-(2,5-difluorobenzyl)-2-(1H-1,2,4-triazol-1-yl)acetamide (CAS 866149-89-5), molecular formula C11H10F2N4O and molecular weight 252.22 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
