Used primarily in research settings as a selective antagonist for adenosine receptors, particularly the A1 subtype. This property makes it valuable in studies related to cardiovascular function, neurotransmission, and renal physiology. It helps investigate the role of adenosine in modulating heart rate, blood pressure, and ischemic preconditioning.

Also employed in neurological research to explore adenosine's involvement in sleep regulation, seizures, and neuroprotection. Due to its ability to cross the blood-brain barrier, it is useful in central nervous system studies.

Not used clinically but serves as a tool compound in pharmacological and physiological experiments.
