Thiophene(CAS No.110-02-1), it also can be called Divinylene sulfide; Thiacyclopentadiene; Thiofuran. It belongs to the Product Categories of Thiophenes; Building Blocks; Thiophene; Organoborons; Halogenated; Organohalides; Boronic ester; Carboxy. Thiophenes are important heterocyclic compounds , and they are widely used as building blocks in many agrochemicals and pharmaceuticals. The benzene ring of a biologically active compound may often be replaced by a Thiophene without loss of activity. This is seen in examples such as the NSAID lornoxicam, the Thiophene analog of piroxicam.
