Ethyl pentafluorobenzoate is primarily used as a reagent in organic synthesis, particularly in the preparation of more complex fluorinated compounds. It serves as a key intermediate in the production of pharmaceuticals, agrochemicals, and specialty chemicals where the introduction of fluorine atoms is required to enhance stability, bioavailability, or other desired properties. Additionally, it is employed in the development of liquid crystals and advanced materials, leveraging its unique fluorinated structure to modify physical and chemical characteristics. Its role in cross-coupling reactions and as a building block in the synthesis of aromatic fluorinated esters makes it valuable in research and industrial applications.
