Used primarily in pharmaceutical research and development, it serves as an intermediate in the synthesis of various active pharmaceutical ingredients (APIs). Its role is crucial in the production of compounds targeting neurological disorders, where it aids in the creation of molecules that interact with specific receptors in the brain. Additionally, it is utilized in the development of small molecule drugs for treating conditions like depression, anxiety, and chronic pain. Its hydrochloride form enhances solubility, making it more effective in drug formulation processes. Researchers also employ it in peptide synthesis and as a building block for designing novel therapeutic agents.
