Chemical Structure
Description
The occurrence of (3aR,6R,7aR)-7,7-Dichloro-8,8-dimethylhexahydro-3H-3a,6-methanobenzo[c]isothiazole 2,2-dioxide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (3aR,6R,7aR)-7,7-Dichloro-8,8-dimethylhexahydro-3H-3a,6-methanobenzo[c]isothiazole 2,2-dioxide (CAS 204854-09-1), a certified reference material (molecular formula C10H15Cl2NO2S, MW 284.20 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (3aR,6R,7aR)-7,7-Dichloro-8,8-dimethylhexahydro-3H-3a,6-methanobenzo[c]isothiazole 2,2-dioxide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
