Description

(R)-Quizalofop Methyl is the biologically active R-enantiomer of the selective aryloxyphenoxypropionate herbicide quizalofop-methyl. This high-purity chiral compound is critical for developing advanced, more efficient, and environmentally targeted post-emergence grass weed control solutions. It is primarily required by agrochemical manufacturers and formulators for the production of next-generation selective herbicides used in broadleaf crops such as soybeans, cotton, and oilseed rape.

Application

• Active Ingredient in Herbicide Formulations: Serves as the key chiral active component in emulsifiable concentrates (EC), suspension concentrates (SC), and other formulations for superior grass weed control.
• Selective Post-Emergence Weed Management: Specifically targets annual and perennial grassy weeds (e.g., barnyard grass, crabgrass, foxtails) in sensitive dicotyledonous crops without harming the crop itself.
• Agrochemical Intermediate: Used in the synthesis and purification of advanced herbicide products where the isolated (R)-enantiomer provides the desired herbicidal activity.
• Research & Development: Employed in agricultural research institutions and corporate R&D labs for developing new enantiopure agrochemicals, studying mode of action, and evaluating environmental fate.
• Manufacturing of Enantiomerically Pure Products: Essential for companies specializing in chiral chemistry and the production of single-isomer agrochemicals to minimize environmental load and enhance efficacy.
