Used primarily in medical research and diagnostics, particularly in the field of nuclear medicine. It serves as a precursor in the synthesis of radiopharmaceuticals, such as meta-iodobenzylguanidine (MIBG), which is employed for imaging and treating neuroendocrine tumors. Its ability to target specific tissues makes it valuable for detecting and monitoring conditions like pheochromocytoma and neuroblastoma. Additionally, it plays a role in studying adrenergic systems and related physiological processes.
