Bi- and oligothiophenes are organic compounds containing two or more linked thiophene rings. Thiophene is a five-member aromatic ring with one sulfur and four carbon atoms. Arctinal is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Arctinal can be found in burdock, which makes arctinal a potential biomarker for the consumption of this food product.
