Фентрифанил

Description

Fentrifanil (CAS 62441-54-7, formula C14H6ClF6N3O4) is a chloro-trifluoromethyl-substituted dinitro derivative of diphenylamine (N-[2-chloro-5-(trifluoromethyl)phenyl]-2,4-dinitro-6-(trifluoromethyl)aniline), in English-language sources appears under the names Fentrifanil, Famaflur, Fluofenamine, Flufenamine, code PP 199. Second systematic name: 2'-chloro-2,4-dinitro-5',6-bis(trifluoromethyl)diphenylamine. In the original table it is classified under the “Amides” section. It is registered in registers of pesticide active substances (including in the list of the state of Maine, USA), however, reliable data on the specific agricultural purpose and mechanism of action was not found in open sources, so this information is not provided - the rule is not to replace a missing fact with an assumption by analogy.

Substance class

Structurally, it belongs to diphenylamine derivatives (diarylamines) with electron-withdrawing substituents - chlorine, two trifluoromethyl groups and two nitro groups. This structure is typical for contact pesticide active substances synthesized as analogues of nitrophenol and nitroaniline compounds. The high XLogP3 value (7.057) indicates the pronounced lipophilicity of the molecule - it is poorly soluble in water and tends to accumulate in non-polar media, which is typical for halogen-substituted aromatic amines.

Scope of application

The name appears on pesticide registration lists; used as a technical active substance in the chemical industry in the production of plant protection products. Specific target crops and pests are not listed in the verified sources - this section is deliberately left incomplete so as not to substitute typical values ​​for similar diarylamines.

Storage and transportation

Due to its high flash point (179 °C), the substance is relatively thermally stable under normal storage conditions. It is recommended to store in the original container in a cool, dry place, away from sources of open flame, taking into account the general requirements for the storage of technical pesticide substances. Additional toxicity parameters, UN transport codes and GHS classification (H- and P-phrases) are not present in the original dump and were not found in the available databases - these columns are deliberately not filled with fictitious values.
