Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors. It serves as a building block in medicinal chemistry due to its ability to mimic arginine residues, making it valuable in designing enzyme inhibitors. Commonly employed in research for creating compounds that target serine proteases, which are involved in diseases like thrombosis, inflammation, and viral infections. Also utilized in the preparation of labeled derivatives for biochemical assays and imaging studies. Its fluorinated structure enhances binding selectivity and metabolic stability in drug candidates.
