(1E)-N′-[4-Cyano-1-(3,4-dichlorophenyl)-1H-pyrazol-5-yl]-N,N-dimethylmethanimidamide (CAS 956930-25-9), molecular formula C13H11Cl2N6O and molecular weight 338.17 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (1E)-N′-[4-Cyano-1-(3,4-dichlorophenyl)-1H-pyrazol-5-yl]-N,N-dimethylmethanimidamide (C13H11Cl2N6O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.5, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 338.17 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.
