Used as a selective antagonist of P2X1 and P2X3 purinergic receptors, making it valuable in research on pain signaling and neurotransmission. It helps investigate the role of ATP-gated ion channels in cellular communication, particularly in sensory neurons and platelet activation. Due to its high selectivity, it is employed in studies aiming to differentiate receptor subtype functions in inflammatory and neuropathic pain models. Its water solubility and stability in physiological conditions make it suitable for in vitro and in vivo pharmacological experiments.
