Chemical Structure
Fenpyrazone
- CAS No.: 1992017-55-6
- Formula:C22H22ClF3N4O6S
- Molecular Weight:562.95
IUPAC Name: 4-(2-chloro-4-(methylsulfonyl)-3-((2,2,2-trifluoroethoxy)methyl)benzoyl)-1-ethyl-1H-pyrazol-5-yl 1,3-dimethyl-1H-pyrazole-4-carboxylate
InChIKey: NWBFHIJKEYFVND-UHFFFAOYSA-N
SMILES: O=C(C1=CN(C)N=C1C)OC2=C(C(C3=CC=C(S(=O)(C)=O)C(COCC(F)(F)F)=C3Cl)=O)C=NN2CC
Biological Activity: Fenpyrazone is a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor as well as a post-emergence herbicide. By inhibiting the activity of HPPD, Fenpyrazone indirectly blocks carotenoid biosynthesis in plants, causing bleaching of new tissues in sensitive plants, followed by necrosis and eventual death. Fenpyrazone is used in studies on controlling annual monocotyledonous and dicotyledonous weeds in summer maize fields[1].
