Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antidiabetic and antihypertensive drugs. Its structure allows for selective functionalization, making it valuable in constructing complex bioactive molecules. Commonly employed in the preparation of tyrosine kinase inhibitors and other enzyme-targeting therapeutics. Also utilized in agrochemical synthesis for creating herbicides and fungicides due to its halogenated aromatic framework. Its aldehyde group facilitates condensation reactions, enabling the formation of Schiff bases and other derivatives in medicinal chemistry research.
