CAS 7446-08-4: Selenium dioxide

Selenium dioxide is a chemical compound that contains selenium and oxygen. It is used to create particle size of less than 1 micrometer, which has many applications in various industries. Selenium dioxide can be used as a catalyst for the production of polymers such as polyethylene, polystyrene, and polypropylene. It also has the ability to control the metabolic disorders caused by bacteria. Selenium dioxide has been shown to induce apoptosis by activating caspases and inhibiting nitric oxide synthase in animal cells. Selenium dioxide has been shown to have anti-inflammatory properties due to its antioxidant effects and ability to regulate immune system activity. Selenium dioxide can be detected using an analytical method called laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS).
