(±)-Fluazifop-d4

(±)-Fluazifop-d4 is a stable, isotopically labeled analogue of the herbicide (±)-Fluazifop-p-butyl, which is widely used to control grass weeds in various crops. It is a post-emergent herbicide that works by inhibiting the activity of acetyl-CoA carboxylase (ACCase), an enzyme that is essential for fatty acid synthesis in plants. This leads to the disruption of cell membrane integrity and ultimately, the death of the plant. The chemical structure of (±)-Fluazifop-d4 consists of a p-butylphenoxy group attached to a cyclohexanedione moiety, with four deuterium atoms incorporated into the molecule. The deuterium labeling improves the analytical sensitivity and specificity of the compound, making it useful for pharmacokinetic and metabolism studies. When applied to crops, (±)-Fluazifop-d4 is rapidly absorbed by the foliage and translocated to the growing points of the plant. It has a relatively short half-life in soil and water, and is not expected to persist in the environment. However, it is important to follow the recommended application rates and safety precautions to minimize the risk of off-target effects and environmental contamination. Overall, (±)-Fluazifop-d4 is a valuable tool for researchers and regulatory agencies to better understand the fate and behavior of (±)-Fluazifop-p-butyl in the environment, and to develop effective strategies for weed management in agriculture.
