This chemical is primarily utilized in pharmaceutical research and development as a key intermediate in the synthesis of bioactive compounds. Its structure, featuring a spiro[indoline-3,4'-piperidine] core, makes it valuable for constructing complex molecules, particularly those targeting neurological and psychiatric disorders. It is often employed in the development of potential drug candidates for conditions such as depression, anxiety, and schizophrenia, due to its ability to interact with specific receptors in the brain. Additionally, its tert-butyl carboxylate group provides stability and facilitates further chemical modifications, making it a versatile building block in medicinal chemistry.
