RU-TRAAK-2 is primarily used in research settings to study the function and regulation of potassium channels, particularly the TWIK-related arachidonic acid-activated potassium (TRAAK) channels. These channels play a critical role in cellular processes such as membrane potential maintenance and neuronal excitability. By modulating TRAAK channels, researchers can investigate their involvement in pain sensation, neuroprotection, and mechanosensitivity. This chemical is valuable for understanding the physiological and pathological roles of these channels, potentially leading to insights into neurological disorders and the development of targeted therapies. Its application is limited to laboratory studies and is not used in clinical or industrial contexts.
