Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents featuring a piperidine core. The tert-butoxycarbonyl (Boc) group protects the nitrogen during synthesis, enabling controlled reactions and enhanced specificity in forming chemical bonds. Its 4-(4-chlorophenyl) and 4-carboxylic acid substituents support the creation of bioactive molecules through further functional group transformations. Commonly employed in medicinal chemistry as a building block for receptor modulators targeting neurological disorders, such as pain, depression, and anxiety. Also utilized in research settings for preparing analogs in structure-activity relationship (SAR) studies.
