Used in research settings as a selective inhibitor of the sodium channel Nav1.7, making it a valuable tool compound for studying pain pathways. It helps scientists investigate the role of Nav1.7 in neuronal signaling, particularly in conditions related to inherited erythromelalgia and other pain disorders. Due to its potency and selectivity, it is employed in preclinical studies to validate Nav1.7 as a therapeutic target for developing new analgesic drugs. Not intended for clinical use or human therapeutics.
