Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its α,β-unsaturated ester structure makes it suitable for Michael addition reactions and other conjugate additions, enabling the construction of complex fluorinated molecules. Commonly employed in the development of bioactive compounds, especially in medicinal chemistry research targeting fluorinated analogs with enhanced metabolic stability and binding affinity. Also utilized in polymer chemistry to introduce fluorinated aromatic segments into specialty materials, improving thermal and chemical resistance.
