| | FENAMIDONE Usage And Synthesis |
| Description | Fenamidone (13; RPA 407213; (S)-5-methyl-2-methylthio-
5-phenyl-3-phenylamino-3,4-dihydroimidazol-4-one) is a complex III inhibitor
that does not derive from the strobilurins but rather
belongs to the imidazolinone chemical class. Fenamidone is a white woolly powder, with the
following characteristics: mp = 137 ?C; water solubility =
7.8 mg/L; logP = 2.8, and vp = 3.4×10?7 Pa. It was
first described by Mercer et al. (39) in 1998. Only the
S-enantiomer shows antifungal activity, thus offering a
reduction in application rates over the racemic mixture. | | Chemical Properties | Pure product is white woolly powder, no typical odor. Relative density 1.288. vapor pressure 3.4×10-4mPa(25℃), distribution coefficient KowlgP=2.8(20℃), Henry's constant 0.5×10-5Pa -m3 /mol(20℃). Solubility in water 7.8 mg/L (20°C). Solubility in organic solvents (20℃,g/L): acetone 250, acetonitrile 86.1, dichloromethane 330, methanol 43, n-octanol 9.7. | | Uses | Fungicide. | | Definition | ChEBI: A member of the class of imidazolones that is 3,5-dihydroimidazol-4-one substituted at position 2 by a methylthiogroup, at position 3 by an anilino group and at position 5 by phenyl and methyl groups (the S-enantiomer). A fungicide effecti
e against Oomycete diseases such as downy mildew and certain leaf spot diseases. | | Hazard | Moderately toxic by ingestion and skin contact. Low toxicity by inhalation. | | Toxicity evaluation | Fenamidone has an acute oral LD50 > 5,000 and an
acute dermal LD50 > 2,000 mg/kg in rats. Fenamidone is
not a skin or eye irritant, is negative in the Ames test, and
is nonteratogenic. It shows low toxicity to birds in acute
and dietary studies but has a 96-h fish LC50 of 0.74 mg/L. |
