Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and bioactive molecules. Its structure allows for selective functionalization, making it valuable in creating herbicides and plant growth regulators. It is also employed in the preparation of pyridine-based compounds with potential antimicrobial and antifungal properties. Due to the presence of reactive halogen groups and an aldehyde functionality, it serves as a versatile building block in cross-coupling reactions and heterocyclic chemistry for drug discovery.
