Used as a potent neurotoxin in scientific research to model neurodegenerative diseases such as Huntington's disease. It induces selective damage to the striatum in the brain by inhibiting mitochondrial succinate dehydrogenase, leading to energy depletion and neuronal cell death. This makes it valuable in studying mechanisms of oxidative stress, excitotoxicity, and potential neuroprotective therapies. Also investigated for its role in understanding stroke and Parkinsonian symptoms in animal models. Due to its high toxicity, it is handled with strict safety controls and not used in industrial or commercial applications outside research settings.
