Used as an intermediate in organic synthesis, particularly in the development of pharmaceutical compounds. It serves as a protected amine derivative, enabling selective reactions in multi-step syntheses. The tert-butyl carbamate group provides stability under various reaction conditions and can be removed selectively to release the free amine when needed. This compound is valuable in medicinal chemistry for constructing complex molecules, especially those involving cyclobutyl and phenyl ring systems, which are found in bioactive molecules and central nervous system agents.
