Product Description

Product Introduction

2,3-Difluoro-5-chloropyridine is an important intermediate for the synthesis of the highly efficient pesticide, cyantraniliprole. In the past decade, fluorinated pesticides have developed rapidly and have become the focus of the development of the world's pesticide industry. Among them, fluorinated pyrethroid and fluorinated benzoate urea insecticides have been developed and applied in large quantities.

Due to the small radius of the fluorine atom in 2,3-difluoro-5-chloropyridine and its large electronegativity, the C-F bond formed by it is much stronger than the C-H bond, significantly enhancing the stability and biological activity of organic fluorine compounds. Moreover, fluorine-containing organic compounds also have high lipid solubility and hydrophobicity, promoting their absorption and transport speed in biological organisms and causing changes in their physiological effects. Therefore, fluorine-containing pesticides have relatively characteristics such as small dosage, low toxicity, and high efficacy in performance. Currently, the development of fluorine-containing pesticides has become the main body of new pesticide creation.
