| Common Name | Lactofen |

| Description | Lactofen belongs to the class of organic compounds known as diphenylethers. These are aromatic compounds containing two benzene rings linked to each other through an ether group. Lactofen is an extremely weak basic (essentially neutral) compound (based on its pKa). Lactofen is a potentially toxic compound. It is used in postemergence applications to certain crops which are resistant to its action. The name 'Lactofen' is approved by the American National Standards Institute and the Weed Science Society of America, and is also approved in China (乳氟禾草灵). Lactofen is a complex ester of acifluorfen and is a nitrophenyl ether selective herbicide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Lactofen is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Lactofen is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources. |
