Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Methyl 5,6-dihydro-2H-thiopyran-3-carboxylate 1,1-dioxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.22 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).
