General description

Thianaphthene-2-carboxylic acid, a benzothiophene,[1] is a heterocyclic sulfur compound. It undergoes degradation (23%) by employing a mixture of washed cells of Rhodococcus erythropolis DS-3 and Gordonia sp. C-6.[2]

Application

Thianaphthene-2-carboxylic acid may be used for the fabrication of carboxylated conducting polymer/CNTs (carbon nanotubes) composites thin films.[1]
