Used as an inhibitor of NADPH oxidase enzymes, making it valuable in research to study reactive oxygen species (ROS) production in cellular systems. It helps investigate the role of ROS in signaling pathways, inflammation, and oxidative stress-related diseases. Commonly applied in immunology, neuroscience, and cardiovascular research to probe enzyme mechanisms and cellular responses. Also used to suppress superoxide generation in cell culture experiments, aiding in the clarification of redox-dependent processes.
