Pentachlorobenzenethiol is a chemical compound from the group of thiols and organochlorine compounds.[1] The chemical formula is C
6HCl
5S.[2]

Synthesis

Pentachlorobenzenethiol can be obtained from hexachlorobenzene.[3]

Properties

Pentachlorobenzenethiol is a combustible gray solid with an unpleasant odor, practically insoluble in water. It has a monoclinic crystal structure.[4] The compound is not well-biodegradable and presumably bioaccumulable and toxic for aquatic organisms. Pentachlorobenzenethiol is itself a metabolite of hexachlorobenzene and is found in the urine and the excretions of animals receiving hexachlorobenzene.[5] Pentachlorobenzenethiol has a high potential for long-range transport via air as it is very slowly degraded in atmosphere.[6]

Applications

Pentachlorobenzenethiol is used in the rubber industry. The compound is added to rubber (both natural and synthetic) to facilitate processing (mastication).
