Chemical Structure

4-Methanesulfonylbenzene-1-thiol CAS 3814-25-3 chemical structure

Description

Structurally, 4-Methanesulfonylbenzene-1-thiol (C7H8O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 188.27 g/mol, it falls into the medium-molecular-weight range. 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).
