Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals due to the presence of both a carboxylic acid group and a trifluoromethyl-substituted double bond. The electron-withdrawing trifluoromethyl group enhances reactivity in conjugate addition reactions, making it valuable in building fluorinated organic molecules. It is also employed in polymer chemistry to introduce fluorinated segments into copolymers, improving thermal stability, chemical resistance, and hydrophobicity. Additionally, it serves as a building block in the development of specialty materials, including coatings and electronic chemicals, where fluorine content contributes to desired surface and dielectric properties.
