Used in research settings as a potent and selective inhibitor of myeloperoxidase (MPO), an enzyme involved in inflammatory processes. Helps in studying oxidative stress and inflammation-related pathways, particularly in models of cardiovascular disease, neurodegeneration, and autoimmune disorders. Due to its selectivity, it is valuable for probing MPO's role without significantly affecting other peroxidases. Also considered in the development of therapeutic strategies targeting MPO-driven tissue damage.
