Coenzyme Q2 is primarily utilized in research settings to study cellular respiration and energy production mechanisms. It serves as a model compound to understand the role of coenzyme Q analogs in mitochondrial electron transport chains. In biochemical studies, it helps elucidate the antioxidant properties and membrane-stabilizing functions of coenzyme Q series compounds. Additionally, it is used in experimental models to investigate the impact of coenzyme Q variants on oxidative stress and aging processes. Its applications are largely confined to laboratory research rather than commercial or therapeutic use.
