Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical industry. It serves as a key building block for preparing bioactive molecules and drug candidates due to its ability to form amide and ester derivatives. Commonly employed in the development of agrochemicals, fungicides, and herbicides because of the pyridine ring’s favorable electronic properties and the reactivity of the acid chloride group. Also utilized in the synthesis of ligands for catalysis and in the preparation of functionalized pyridine derivatives used in materials science. Its bromine substituent allows for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, enhancing its versatility in complex molecule assembly.
