Used as an intermediate in the synthesis of liquid crystal materials for display technologies. It plays a key role in the production of certain pharmaceuticals, particularly in the development of angiotensin II receptor antagonists used to treat hypertension. Its structure allows for effective conjugation in organic semiconductors, making it valuable in some optoelectronic applications. Also employed in research settings for the preparation of fluorescent dyes and sensors due to its aromatic and aldehyde functional group reactivity.
