Used as an intermediate in organic synthesis, particularly in the preparation of Schiff bases and heterocyclic compounds. It serves as a ligand in coordination chemistry, forming complexes with metal ions that are useful in catalysis. Also employed in the development of dyes and pigments due to its conjugated structure and ability to absorb visible light. Its derivative compounds show potential in pharmaceutical research, including antimicrobial and anticancer activities. Additionally, it finds use in the study of photochemical reactions and molecular switches due to its reversible isomerization under light exposure.
