Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structure supports the creation of compounds with enhanced metabolic stability and blood-brain barrier penetration. Commonly employed in medicinal chemistry for optimizing lead compounds due to the tert-butyl carbamate group, which acts as a protected amine, allowing selective deprotection and further functionalization. Also utilized in the preparation of protease inhibitors and receptor modulators where the trifluoromethoxy phenyl moiety contributes to improved binding affinity and lipophilicity.
