m-Tyramine hydrobromide is primarily utilized in biochemical research as a reagent to study adrenergic receptors and neurotransmitter systems. It acts as a substrate for enzymes like monoamine oxidase, helping researchers understand the metabolism of biogenic amines. This compound is also employed in pharmacological studies to investigate its effects on blood pressure and heart rate due to its sympathomimetic properties. Additionally, it serves as a reference standard in analytical chemistry for the identification and quantification of tyramine derivatives in various biological samples. Its role in exploring the mechanisms of neurotransmitter release and receptor interactions makes it valuable in neuroscience and drug development research.
