Used in pharmaceutical research as a key intermediate in the synthesis of various bioactive compounds. It plays a role in the development of drugs targeting neurological disorders, including Alzheimer's disease and Parkinson's disease, due to its structural similarity to neurotransmitters. Additionally, it is utilized in the preparation of small molecule inhibitors for enzymes and receptors involved in inflammatory and metabolic pathways. Its hydrochloride form enhances solubility, making it suitable for use in experimental formulations and drug delivery systems.
