Description

Oxyfluorfen (CAS 42874-03-3) is a highly effective diphenyl ether herbicide with the molecular formula C₁₅H₁₁ClF₃NO₄. Its IUPAC name is 2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene. This selective herbicide is widely used in agricultural and horticultural applications due to its pre- and post-emergence activity against broadleaf weeds and grasses. Oxyfluorfen acts by inhibiting protoporphyrinogen oxidase (PPO), leading to the accumulation of reactive oxygen species and subsequent membrane disruption in target plants.

Our high-purity Oxyfluorfen is synthesized under strict quality control measures, ensuring >98% purity as verified by HPLC analysis. It is supplied as a stable, crystalline solid with low solubility in water but excellent solubility in organic solvents such as acetone and methanol. Suitable for research, formulation development, and analytical standards, this product is packaged under inert conditions to guarantee long-term stability.

Application

Oxyfluorfen is primarily used as a selective herbicide for controlling annual broadleaf weeds and grasses in crops such as cotton, soybeans, and tree nuts. It is applied pre-emergence or early post-emergence, forming a protective barrier in the soil that prevents weed growth. The compound’s mode of action involves inhibition of PPO, disrupting chlorophyll synthesis and causing oxidative damage to plant tissues. Its residual activity makes it effective for long-term weed management while maintaining crop safety when used as directed.
