(±)-Fluazifop-d3 (methyl-d3)

(±)-Fluazifop-d3 (methyl-d3) is a deuterated derivative of the herbicide fluazifop-p-butyl. It is a selective post-emergent herbicide that is used to control annual and perennial grass weeds in a wide range of crops, including soybeans, cotton, peanuts, and vegetables. The deuterium substitution in the molecule provides a useful analytical tool for studying the fate and behavior of the herbicide in the environment. The active ingredient in (±)-Fluazifop-d3 (methyl-d3) works by inhibiting the enzyme acetyl-CoA carboxylase (ACCase), which is essential for fatty acid synthesis in plants. This leads to the accumulation of toxic levels of fatty acids and subsequent cell death in the targeted grass weeds. The herbicide is absorbed through the leaves of the plant and translocated to the growing points, where it exerts its herbicidal activity. (±)-Fluazifop-d3 (methyl-d3) has a low toxicity to mammals and is classified as a Group C (possible human carcinogen) by the US Environmental Protection Agency. It has a short half-life in soil and water, which reduces the risk of environmental contamination. However, it can be toxic to aquatic organisms and should be used with caution near water bodies. Overall, (±)-Fluazifop-d3 (methyl-d3) is an effective herbicide that is widely used in agriculture to control grass weeds. Its deuterium substitution provides a useful analytical tool for studying its fate and behavior in the environment.
