2-Chloro-3-fluoropyridine丨CAS 17282-04-1

2-Chloro-3-fluoropyridine is a valuable halogenated pyridine derivative widely applied as an intermediate in pharmaceutical, agrochemical, and fine chemical synthesis. It is commonly used in the preparation of active pharmaceutical ingredients (APIs), serving as a building block for drugs targeting inflammation, cancer, and infectious diseases. In agrochemicals, it contributes to the development of herbicides, fungicides, and insecticides due to its heteroaryl scaffold and reactivity. It is also employed in materials chemistry, where its halogen functionalities enable cross-coupling reactions such as Suzuki or Buchwald-Hartwig reactions, facilitating the creation of advanced heterocyclic compounds.

The benefits of 2-Chloro-3-fluoropyridine stem from its dual halogen substitution, which enhances reactivity and selectivity in synthetic transformations. The chlorine and fluorine atoms provide versatile functional handles for substitution and coupling reactions, enabling efficient derivatization. Its pyridine core imparts stability and desirable electronic properties, making it a reliable intermediate for synthesizing bioactive molecules. Additionally, its compatibility with modern synthetic methods, such as palladium-catalyzed coupling, makes it a cost-effective and scalable choice for industrial applications.
