Used in research to study mitochondrial function, particularly as an inhibitor of the adenine nucleotide translocator (ANT) in the inner mitochondrial membrane. It helps investigate mechanisms of oxidative phosphorylation and mitochondrial permeability transition pore formation. Due to its high toxicity, it is not used in clinical or industrial applications but serves as a tool compound in biochemical assays to induce mitochondrial dysfunction and cell death in experimental models.
