Chemical Structure

6-Chloro-7-(difluoromethoxy)-1H-indole-3-sulfonyl chloride CAS 2231234-59-4 chemical structure

Description

The occurrence of 6-Chloro-7-(difluoromethoxy)-1H-indole-3-sulfonyl chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Chloro-7-(difluoromethoxy)-1H-indole-3-sulfonyl chloride (CAS 2231234-59-4) is a high-purity analytical reference standard with the molecular formula C9H5Cl2F2NO3S and a molecular weight of 316.11 g/mol.

6-Chloro-7-(difluoromethoxy)-1H-indole-3-sulfonyl chloride (C9H5Cl2F2NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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.
