Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive and antiviral drugs. Its aldehyde functional group allows for easy modification in multi-step organic reactions, making it valuable in medicinal chemistry. Also employed in the development of agrochemicals, including herbicides and fungicides, due to its reactive aromatic structure. Additionally, it serves as a building block in the preparation of conjugated organic materials for electronic applications such as organic semiconductors and sensors.
