product description

Nitric oxide is a colorless , flammable gas with a slight odor .Nitric oxide is poorly soluble in water at room temperature but can dissolve in some organic solvents.NO has a relatively low thermal conductivity, which is typical for diatomic gases.As a gas, the viscosity of nitric oxide is low and behaves similarly to other gases in this regard.Nitric oxide is a reactive molecule and can easily form nitrogen dioxide (NO2) when exposed to oxygen. It can also react with various organic compounds and metals.NO is used in the synthesis of various nitrogen-containing compounds, including fertilizers and explosives.It is also used in the industrial process of nitric acid production.In biology, nitric oxide is a signaling molecule involved in many physiological processes.Nitric oxide is toxic and can displace oxygen in the blood, leading to a condition known as hypoxia. It is important to handle nitric oxide with appropriate safety measures, including proper ventilation and personal protective equipment (PPE).Due to its reactivity with oxygen, care must be taken to prevent the formation of nitrogen dioxide, which is a respiratory irritant and can contribute to acid rain.

Applications

· As a component in calibration gas mixtures for environmental monitoring systems 
· As a component in calibration gas mixtures for industrial hygiene gas mixtures 
· In semiconductor application processes 
· In a very diluted form for medical-related disorders.
