1. Polymers & Resins

• Reagent: it is used in polymer chemistry as a building block and reactant in various reactions, particularly for forming new C-N bonds and in cross-coupling reactions. 
• Intermediate: It's also used in the synthesis of other molecules, including those with thiol functional groups, and in the production of some polymers, such as polyaniline derivatives. 

2. Pharmaceuticals

• Intermediate: It is used in the pharmaceutical industry as a valuable intermediate in the synthesis of various drug molecules. Its bromine-substituted pyridine ring serves as a building block for bioactive compounds, including antimalarial agents and beta-adrenoceptor agonists. 

3. Agrochemicals

• Intermediate: It is used in agrochemicals primarily as an intermediate in the synthesis of other compounds, rather than as a direct pesticide itself. It's a building block for creating more complex molecules with pesticidal properties. 

4. Performance Chemicals

• Intermediate: It is a useful building block in organic synthesis, particularly for introducing a 2-pyridyl group into molecules. It can be used in various cross-coupling reactions, like the Stille coupling and Negishi coupling, to form new C-N bonds. 
• Reagent: Be converted to 2-lithiopyridine, a versatile reagent, and utilized in the synthesis of compounds with thiol functional groups.
