Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its conjugated structure makes it suitable for Michael addition reactions and cycloadditions, enabling the construction of complex cyclic frameworks. Commonly employed in the development of bioactive molecules, including anti-inflammatory and antimicrobial agents. Also utilized in the synthesis of specialty polymers and as a building block in the design of metal-organic frameworks (MOFs) due to its ability to chelate metal ions.
