Ethyl Nitrite vs. Nitroethane — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Published on March 4, 2024
Ethyl nitrite is an organic compound used as a vasodilator and in perfumery, characterized by its formula C2H5ONO. Nitroethane, C2H5NO2, is an organic solvent used in industrial applications, distinct for its nitro group attached to an ethane backbone.

Key Differences
Ethyl nitrite, with the chemical formula C2H5ONO, is known for its applications in medicine as a vasodilator and in the fragrance industry. It acts by relaxing blood vessels, which can help to alleviate chest pain and support other therapeutic effects. Its distinctive sweet smell also makes it useful in perfumery and flavorings.
Nitroethane, C2H5NO2, serves a different purpose, primarily used as a solvent in industrial settings, including the synthesis of other chemicals. Its structure features a nitro group (-NO2) attached to an ethane molecule, giving it properties suited for applications in organic synthesis, adhesives, and coatings.
The key difference between these two compounds lies in their functional groups and resultant uses. Ethyl nitrite's -ONO group facilitates its role in medical and fragrance applications, whereas nitroethane's -NO2 group aligns it with industrial and synthetic uses.
Despite both compounds containing similar carbon and hydrogen backbones, their chemical behavior and applications diverge significantly due to the differences in their molecular structures. This divergence illustrates the impact of functional groups on the properties and uses of organic compounds.
Ethyl nitrite is volatile and highly flammable, requiring careful handling and storage. Its rapid evaporation at room temperature makes it effective for inhalation therapies. On the other hand, nitroethane's lower volatility and solvent properties make it suitable for more stable industrial applications.
