Description

Isoxadifen (Free Acid) CAS NO 209866-92-2 is a high-purity agrochemical intermediate belonging to the chemical class of isoxazole derivatives. This compound is valued for its role as a highly effective herbicide safener, protecting crop plants from phytotoxic damage caused by certain herbicides. It is primarily required by agrochemical manufacturers and formulators developing advanced crop protection solutions. The product is supplied to meet the stringent quality demands of industrial-scale synthesis and formulation processes.

Application

• Herbicide Safener in Crop Protection: Used to selectively protect cereal crops like corn (maize) and rice from injury by sulfonylurea and other classes of herbicides.
• Agrochemical Formulation: A key active ingredient or co-formulant in the production of commercial herbicide mixtures and tank-mix additives.
• Chemical Synthesis Intermediate: Serves as a crucial building block for the synthesis of more complex agrochemical active ingredients and derivatives.
• Research & Development: Utilized in agricultural R&D for developing new safener technologies and studying plant metabolism and detoxification pathways.
