Pentachlorobenzene is a chemical compound that is used as an intermediate in the production of the fungicide pentachloronitrobenzene and can also be found as an impurity in its formulations. Additionally, it has applications as a fire retardant.

Pentachlorobenzene (PeCB) (608-93-5) is a known persistent organic pollutant (POP) and banned globally by the Stockholm Convention on Persistent Organic Pollutants in 2009 (EMBL-EBI, 2023). Pentachlorobenzene has historically been used as an intermediate in the synthesis of several pesticides, in particular the fungicide pentachloronitrobenzene.
