Used as a key intermediate in the synthesis of histamine H3 receptor antagonists, which are investigated for their potential in treating neurological disorders such as Alzheimer's disease, schizophrenia, and attention deficit hyperactivity disorder (ADHD). Its structure mimics histamine, allowing integration into compounds that modulate histaminergic neurotransmission. Also employed in the development of anti-inflammatory agents and in medicinal chemistry research for designing enzyme inhibitors. Its carboxylic acid functionality enables conjugation to other molecules, enhancing solubility and bioavailability in drug candidates.
