Thiophene is a heterocyclic compound with the formula C4H4S. Consisting of a planar five-membered ring, it is aromatic as indicated by its extensive substitution reactions. It is a colorless liquid with a benzene-like odor. In most of its reactions, it resembles benzene. Compounds analogous to thiophene include furan (C4H4O) selenophene (C4H4Se) and pyrrole (C4H4NH), which each vary by the heteroatom in the ring.

APPLICATION
Thiophene can be used in the production of various kinds of dyes, perfumes, thermal shock resistant plastic, highly active solvent, stimulating hormone, insecticide, brightening agents, cosmetics and bio-activating substances and vitamins, anesthetics and antibiotics. It can also be used as the raw materials of preparing a broad spectrum anthelmintic pyrantel as well as antibacterial drugs cephalosporin I and II. Moreover, it can be used for further preparation of solvents such as sulfolane. Using chemical or electrochemical method can enable the synthesis of polythiophene, and having a conductivity of 2~10.6 × 103S/m after doping, and thus is a kind of conductive polymer materials of potential application.
