2F-422S 321533-95-3 5-chloro-N-[(4-chlorophenyl)methyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carboxamide (CAS 321533-95-3) is a high-purity analytical reference standard with the molecular formula C13H10Cl2F3N3O and a molecular weight of 352.14 g/mol.
Structurally, 2F-422S 321533-95-3 5-chloro-N-[(4-chlorophenyl)methyl]-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carboxamide (C13H10Cl2F3N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 352.14 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
