Ubiquinone-1 is primarily used in research and development settings to study the mechanisms of electron transport in biological systems. It serves as a model compound for understanding the role of coenzyme Q in mitochondrial function and energy production. Additionally, it is employed in biochemical assays to investigate oxidative stress and antioxidant activity. In some cases, it is utilized as a reference standard in analytical chemistry to quantify or identify coenzyme Q derivatives in various samples. Its applications are largely confined to laboratory studies rather than industrial or commercial use.
