About Pentachlorophenol

Pentachlorophenol was widely used as a pesticide and wood preservative. Since 1984, the purchase and use of pentachlorophenol have been restricted to certified applicators. It is no longer available to the general public. It is still used as a wood preservative for utility poles, railroad ties, and wharf pilings.
