(Z)-N'-((2,4-dichlorophenyl)sulfonyl)-2-((1-phenyl-1H-1,2,4-triazol-3-yl)oxy)acetimidamide (CAS 338405-38-2) is a high-purity analytical reference standard with the molecular formula C16H13Cl2N5O3S and a molecular weight of 426.28 g/mol.
The molecular framework of (Z)-N'-((2,4-dichlorophenyl)sulfonyl)-2-((1-phenyl-1H-1,2,4-triazol-3-yl)oxy)acetimidamide (C16H13Cl2N5O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
