Used as a reagent in organic synthesis, particularly in the preparation of pharmaceutical intermediates. It facilitates the introduction of the fluoroethyl group into molecules, which can enhance the biological activity of compounds. Commonly employed in the development of radiopharmaceuticals for positron emission tomography (PET) imaging, aiding in the study of metabolic processes and disease diagnosis. Additionally, it serves as a building block in the synthesis of agrochemicals and specialty chemicals, contributing to the creation of compounds with improved efficacy and stability.
