Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of fluorinated drugs where the fluorine atom enhances metabolic stability and bioavailability. Commonly employed in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules due to its aldehyde and phenolic functional groups, which allow for diverse chemical modifications. Also utilized in the preparation of fluorescent probes and sensors, taking advantage of its ability to form Schiff bases that exhibit luminescent properties. Plays a role in agrochemical synthesis for creating herbicides and fungicides with improved environmental persistence and activity. Its structural features make it suitable for coordination with metal ions in catalytic applications and in the design of metal-organic frameworks (MOFs).
