Chemical Structure
Description
Structurally, 5-Iodothiophene-2-sulfonyl chloride (C4H2ClIO2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 308.54 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).
