C8H9N2O

C8H9N2O is the molecular formula for several chemical compounds, including isomers of acetanilide. Acetanilide itself is a white, crystalline solid with the chemical formula C8H9NO. It is an organic compound that was historically used as an analgesic and antipyretic. Due to its toxicity, it is no longer widely used for medicinal purposes, though it remains important as a chemical intermediate.

Other compounds with the molecular formula C8H9N2O exist. These are isomers, meaning they have the same atoms but arranged differently, leading to different chemical properties. Examples of such isomers might include various substituted anilines or other aromatic amines and amides with additional nitrogen atoms. The specific properties and uses of these isomers would depend on their unique structures.

The synthesis of compounds with this formula often involves reactions with aniline derivatives or modifications of existing nitrogen-containing organic molecules. Understanding the structure of a specific C8H9N2O isomer is crucial for determining its reactivity, physical characteristics, and potential applications in organic chemistry, material science, or as a building block for more complex molecules. Further characterization through techniques like spectroscopy and X-ray crystallography is necessary to definitively identify any specific compound with this molecular formula.
