Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) that target central nervous system disorders. Its aldehyde functional group allows for easy modification in multi-step organic reactions, making it valuable in creating complex nitrogen-containing heterocycles. Commonly employed in the development of antipsychotic, antidepressant, and antihistamine drugs due to its structural compatibility with bioactive molecules. Also utilized in research settings for the preparation of novel piperidine-based compounds for biological screening.
