Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 5-(chlorosulfonyl)-2-(2-methoxyethoxy)benzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.71 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).
