Chemical Structure

4-Bromo-N-({4-ethyl-5-[(2-methylprop-2-en-1-yl)sulfanyl]-4H-1,2,4-triazol-3-yl}methyl)benzene-1-sulfonamide CAS 338794-56-2 chemical structure

Description

4-Bromo-N-({4-ethyl-5-[(2-methylprop-2-en-1-yl)sulfanyl]-4H-1,2,4-triazol-3-yl}methyl)benzene-1-sulfonamide (C15H19BrN4O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.

4-Bromo-N-({4-ethyl-5-[(2-methylprop-2-en-1-yl)sulfanyl]-4H-1,2,4-triazol-3-yl}methyl)benzene-1-sulfonamide (CAS 338794-56-2), molecular formula C15H19BrN4O2S2 and molecular weight 431.37 g/mol, is a CATO reference standard with documented purity and traceability.
