Used in research to study nitric oxide signaling pathways, NOR-3 serves as a nitric oxide donor that spontaneously releases NO in physiological conditions without requiring enzymatic activation. This property makes it valuable for investigating the role of NO in vascular relaxation, neurotransmission, and immune response. It is commonly applied in cellular and tissue studies to induce controlled NO release, helping to explore the mechanisms of NO-mediated cytotoxicity, apoptosis, and vasodilation. Due to its stability and predictable decomposition, NOR-3 is preferred in experiments where consistent and sustained NO generation is required.
