Chemical Structure
Description
Structurally, 7-chlorobenzo[d]thiazole-2(3H)-thione (C7H4ClNS2) contains a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 201.70 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).
