Used primarily as an intermediate in organic synthesis, particularly in the pharmaceutical industry. It serves as a protected form of cyclobutylamine, allowing selective reactions at other functional sites in complex molecule assembly. Commonly employed in the development of active pharmaceutical ingredients where the cyclobutyl group is part of the target structure. Its tert-butoxycarbonyl (Boc) protecting group is easily removed under mild acidic conditions, making it ideal for multi-step syntheses. Also utilized in the preparation of agrochemicals and specialty polymers requiring constrained ring systems.
