This appears to be a cancellation of the EPA registration for all products *containing* pentachlorophenol. My read is that it refers to the specific molecule only; pentachlorophenol laureate does not contain pentachlorophenol just as styrene does not contain benzene.

Pentachlorophenol and its salts and esters are listed in Annex I to Regulation 2019/1021 implementing the Stockholm Convention on Persistent Organic Pollutants, and so are banned in the EU. https://ec.europa.eu/info/law/better-regulation/have-your-say/initiatives/12516-Chemical-pollutants-new-limits-for-pentachlorophenol_en  See also http://www.pic.int/Portals/5/DGDs/DGD_Pentachlorophenol_EN.pdf 

The EPA has contact info of Peter Bergquist regarding this, so you might just want to contact him directly. See https://www.govinfo.gov/content/pkg/FR-2022-02-04/html/2022-02418.htm  I don't see anything in the Federal Register addressing registration of derivatives. In fact, the document mentions there are only four registered antimicrobial products containing pentachlorophenol as an active ingredient, so it certainly looks like they are acting only on that one chemical. https://www.regulations.gov/document/EPA-HQ-OPP-2014-0653-0071  The regulation appears narrowly targeted to its use in wood preservation products only.

Has anyone read over this reg?  I don't have time.  But the same kind of regulation was proposed in the 1980s and the manufacturers of on art conservation product just switched to pentachlorophenol laureate and keep selling it.  Is this reg going to apply to pentachlorophenol's many siblings?

EPA AXES PENTACHLOROPHENOL WOOD PRESERVATIVE
Tags: public, discovery, environmental, illegal, pesticides

Companies can produce, distribute, and sell the wood preservative pentachlorophenol in the US for only 2 more years, the US Environmental Protection Agency announced Feb. 4. Wood treatment facilities, however, have until 2027 to use up their existing stocks of the chemical. The National Toxicology Program lists pentachlorophenol as a "reasonably anticipated" human carcinogen. It is banned under the United Nations' Stockholm Convention on Persistent Organic Pollutants, an international treaty the US signed but has not ratified. The EPA claims that pentachlorophenol poses health risks to workers. Alternative wood preservatives-including chromated arsenicals, copper naphthenate, creosote, and dichloro-octyl-isothiazolinone-are available, the EPA says. Environmental groups have been urging the EPA for decades to ban pentachlorophenol. The chemical is persistent in the environment and contaminates about 250 Superfund hazardous waste sites where it was made, according to!
  the advocacy group Beyond Pesticides.
