Chemical Structure
Cyetpyrafen
- CAS No.: 1253429-01-4
- Formula:C24H31N3O2
- Molecular Weight:393.53
IUPAC Name: (Z)-2-(4-(tert-butyl)phenyl)-2-cyano-1-(1-ethyl-3-methyl-1H-pyrazol-5-yl)vinyl pivalate
InChIKey: NWXGXRHWQUMXHA-XUTLUUPISA-N
SMILES: C(=C(\C#N)/C1=CC=C(C(C)(C)C)C=C1)(\OC(C(C)(C)C)=O)/C=2N(CC)N=C(C)C2
Biological Activity: Cyetpyrafen is a pyrazole insecticide/acaricide with broad-spectrum insecticidal activity. Cyetpyrafen binds to DhelOBP4 (Ki = 4.95 μM) and DhelOBP21 (Ki = 5.51 μM) to mediate olfactory recognition in *Cryptolaemus montrouzieri*. Cyetpyrafen induces dose-dependent electroantennogram responses in *Cryptolaemus montrouzieri* and exhibits repellent effects on the species. Cyetpyrafen has bioaccumulative properties, is rapidly and passively absorbed by the roots of lettuce and rice, reaches a steady state within 24 h, preferentially accumulates in roots, and shows limited xylem/phloem translocation[1][2].
