N'1-(2-chloroacetyl)-2-{5-[3-(trifluoromethyl)phenyl]-2H-1,2,3,4-tetraazol-2-yl}ethanohydrazide (CAS 680214-91-9), molecular formula C12H10ClF3N6O2 and molecular weight 362.70 g/mol, is a CATO reference standard with documented purity and traceability.
N'1-(2-chloroacetyl)-2-{5-[3-(trifluoromethyl)phenyl]-2H-1,2,3,4-tetraazol-2-yl}ethanohydrazide (C12H10ClF3N6O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
