Synonym(s): NC-656
- CAS No.: 1994348-72-9
- Formula:C15H15F3N6O4S
- Molecular Weight:432.38
InChIKey: ODXFUPRPCAYZLK-UHFFFAOYSA-N
SMILES: CC1=NN=C(O1)NC(C2=CC=C(N3C(CS(=O)(C(C)C)=O)=NN=C23)C(F)(F)F)=O
Biological Activity: Iptriazopyrid is a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor, with a Ki value of 24.3 nM against Arabidopsis thaliana and 33.3 nM against Oryza sativa. Iptriazopyrid binds to the active pocket of HPPD, occupies the catalytic site, inhibits carotenoid biosynthesis, prevents chloroplast formation, and induces albino and chlorotic symptoms in sensitive plants. Used as a herbicide, Iptriazopyrid can control barnyardgrass when applied alone, and its efficacy does not decrease when mixed with labeled residual herbicides. When Iptriazopyrid is mixed with 2,4-D or triclopyr, its barnyardgrass control effect shows an antagonistic effect. Iptriazopyrid is a triazole carboxamide herbicide that exhibits selectivity for Oryza sativa over Echinochloa crus-galli, and has partial tank-mix compatibility with synthetic auxin herbicides registered for rice[1][2].
