Used in research to induce ferroptosis, a form of regulated cell death linked to iron metabolism and lipid peroxidation. Helps study cancer cell vulnerability, especially in cells dependent on glutathione peroxidase 4 (GPX4) for survival. Also applied in exploring therapeutic strategies for tumors resistant to conventional treatments. Investigated for combination therapies with other pro-oxidant or targeted agents to enhance anti-tumor effects. Not used in clinical medicine; strictly a laboratory tool for mechanistic studies.
