Chemical Structure
Description
The occurrence of 4-(3-(4-Chlorophenyl)-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(3-(4-Chlorophenyl)-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonamide (CAS 2744-49-2) is a high-purity analytical reference standard with the molecular formula C15H14ClN3O2S and a molecular weight of 335.81 g/mol.
4-(3-(4-Chlorophenyl)-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonamide (C15H14ClN3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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.
