Ethyl 2,3,4-trifluorobenzoate is primarily used as an intermediate in the synthesis of more complex chemical compounds, particularly in the pharmaceutical and agrochemical industries. Its three fluoro substituents on the benzene ring make it valuable in the development of active ingredients for drugs and pesticides, where fluorine atoms enhance stability and bioavailability. It is also employed in organic synthesis for the preparation of fluorinated aromatic compounds, which are essential in materials science for creating specialty polymers and coatings with unique properties. Additionally, it serves as a building block in research and development for exploring new chemical reactions and pathways.
