Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where piperidine derivatives are required. Its tert-butyl ester group allows for selective protection of the carboxylic acid functionality during multi-step reactions, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in the preparation of drugs targeting central nervous system disorders, including antidepressants and antipsychotics. Also utilized in agrochemical synthesis for creating structurally diverse compounds with biological activity.
