Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where protected amino alcohols are required. The BOC-protected amine allows for selective reactivity during multi-step syntheses, making it valuable in creating complex drug molecules. Commonly employed in medicinal chemistry for building blocks in protease inhibitors, receptor agonists, or antagonists. Also utilized in the preparation of labeled compounds for metabolic studies or as a scaffold in combinatorial chemistry.
