Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its structure allows for selective functionalization, making it valuable in creating complex heterocyclic compounds. It is also employed in research for the preparation of pyridine-based ligands used in catalysis. Due to the presence of both aldehyde and bromo groups, it enables versatile coupling reactions, including Suzuki and Wittig reactions, facilitating the construction of larger bioactive molecules.
