Used primarily as a cholinergic agent in scientific research, this compound acts as a selective agonist at muscarinic acetylcholine receptors. It is employed in pharmacological studies to investigate cholinergic signaling pathways, particularly in the central nervous system. Researchers utilize it to mimic acetylcholine effects in neuronal tissues, helping to study mechanisms related to memory, learning, and neurodegenerative conditions. Its stability and receptor specificity make it valuable in receptor binding assays and functional studies of G-protein coupled receptors.
