N-Oxide refers to a class of chemical compounds that contain nitrogen and oxygen. These compounds can vary in structure and properties, and they are often used in various applications, including pharmaceuticals and industrial processes. N-Oxides can be formed through the oxidation of nitrogen-containing compounds, and they play a role in environmental chemistry, particularly in the formation of pollutants. One common example of an N-Oxide is nitric oxide (NO), which is important in biological systems and acts as a signaling molecule. Another example is nitrogen dioxide (NO2), a significant air pollutant that can contribute to smog and respiratory issues. Understanding N-Oxides is crucial for both environmental science and health.
