Chemical Structure
Description
5-Chloro-4-{[(2-chlorophenyl)sulfanyl]methyl}-3-{[(4-chlorophenyl)sulfanyl]methyl}-1-methyl-1H-pyrazole (C18H15Cl3N2S2) 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.
CATO supplies 5-Chloro-4-{[(2-chlorophenyl)sulfanyl]methyl}-3-{[(4-chlorophenyl)sulfanyl]methyl}-1-methyl-1H-pyrazole (CAS 318234-34-3), a certified reference material (molecular formula C18H15Cl3N2S2, MW 429.81 g/mol) for analytical method development and quality control.
