2-Chloro-4-(phenylthio)-1,3,5-triazine (CAS 61810-06-8) is a high-purity analytical reference standard with the molecular formula C9H6ClN3S and a molecular weight of 223.68 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 2-Chloro-4-(phenylthio)-1,3,5-triazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 223.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
