3,4-Dichloro-N-[(E)-2-[6-methyl-3-(methylsulfanyl)-1,2,4-triazin-5-yl]ethenyl]aniline (CAS 306980-29-0) is a high-purity analytical reference standard with the molecular formula C13H12Cl2N4S and a molecular weight of 327.23 g/mol.
The molecular framework of 3,4-Dichloro-N-[(E)-2-[6-methyl-3-(methylsulfanyl)-1,2,4-triazin-5-yl]ethenyl]aniline (C13H12Cl2N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
