Chemical Structure

2-Dodecylbenzenesulphonic Acid CAS 47221-31-8 chemical structure

Description

Structurally, 2-Dodecylbenzenesulphonic Acid (C18H30O3S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. 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 326.49 g/mol, it falls into the moderately-high-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).
