Post-emergence herbicide for control of grassy weeds in broad-leaved crops. Herbicide. | [Definition]
ChEBI: Quizalofop-P-ethyl is an ethyl 2-{4-[(6-chloroquinoxalin-2-yl)oxy]phenoxy}propanoate that has R configuration. A proherbicide for quizalofop-P, it is used to control annual and perennial grass weeds in a variety of crops, including potatoes, sugar beet, peanuts, cotton and flax. It has a role as a proherbicide and an agrochemical. It is an ethyl 2-{4-[(6-chloroquinoxalin-2-yl)oxy]phenoxy}propanoate and a quinoxaline herbicide. It is functionally related to a quizalofop-P. It is an enantiomer of a (S)-quizalofop-ethyl. | [Purification Methods]
This (±)-herbicide forms white crystals from Me2CO/EtOH and sublimes in vacuo. Large quantities can be distilled at high vacuum. Its solubilities at 20o in g/10mL are 0.09 (EtOH), 1.1 (Me2CO), 1.2 (xylene), 2.9 (*C6H6), and is nearly insoluble in H2O (0.3mg/L). The (±)-acid has [95977-28-9]. The R-ester enantiomer has m 76-77o (pale brown crystals from EtOH), [ ] D 20 + 3 5 . 9o (EtOH). It is the more active fatty acid synthase inhibitor (designated DPX-Y6202) used to control grassy weeds in broadleaf crops. |
