Used primarily as an irreversible monoamine oxidase inhibitor (MAOI), it is applied in research settings to study the biochemical pathways and functions of monoamine neurotransmitters. In medical contexts, it has been explored for its potential in treating hypertension due to its ability to inhibit the breakdown of catecholamines, thereby affecting blood pressure regulation. Additionally, it has been investigated for its neuroprotective effects in certain neurological disorders. Its use in clinical practice is limited due to the development of more selective and safer pharmacological agents.
