Chemical Structure
Description
CATO supplies 4-(4-Chlorophenyl)-2,5-dimethyl-2,4-dihydro-3H-1,2,4-triazole-3-thione (CAS 142989-12-6), a certified reference material (molecular formula C10H10ClN3S, MW 239.72 g/mol) for analytical method development and quality control.
4-(4-Chlorophenyl)-2,5-dimethyl-2,4-dihydro-3H-1,2,4-triazole-3-thione (C10H10ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
