Polychlorinated carbazoles

Polychlorinated carbazoles (PCCZ) are a group of chlorinated organic compounds.

They are derivatives of carbazole and nitrogen analogues of polychlorinated dibenzofurans.

Polychlorinated carbazoles usually occur as a mixture of various isomers.

They are formed under certain conditions as by-products of thermal processes.

In environmental samples, mixed halogenated carbazoles are also found.
