Polycyclic aromatic hydrocarbon with three six-membered rings and one five-membered ring with a single sulphur atom
Benzo[b]naphtho[2,1-d]thiophene belongs to the class of sulphur-containing-PAH (S-PAH). It occurs in fossil fuels and is produced by incomplete combustion of organic materials. It can be detected e.g. in emissions from lignite combustion, coal tar derivates, exhausts from diesel engines and lubricant oils.
Benzo[b]naphtho[2,1-d]thiophene is carcinogenic in animal experiments.
