Chemical Structure
Description
The occurrence of 2,3-Dichloro-N,N-dimethylbenzenesulfonamide 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.
2,3-Dichloro-N,N-dimethylbenzenesulfonamide (CAS 865664-00-2) is a high-purity analytical reference standard with the molecular formula C8H9Cl2NO2S and a molecular weight of 254.13 g/mol.
2,3-Dichloro-N,N-dimethylbenzenesulfonamide (C8H9Cl2NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
