Quizalofop-P-ethyl is a selective post-emergence herbicide belonging to the aryloxyphenoxypropionate class. It is used to control annual and perennial grass weeds in broadleaf crops such as soybeans, cotton, peanuts, and vegetables. The compound inhibits acetyl-CoA carboxylase (ACCase), an enzyme essential for fatty acid synthesis in grasses, leading to membrane disruption and plant death. Its (R)-enantiomer configuration enhances potency and selectivity, allowing safe use in dicotyledonous crops. Due to its chiral properties and biological activity, it has also been explored in pharmaceutical research for potential interactions with chiral-sensitive targets.
