C12H11NO

C12H11NO is the molecular formula for several different chemical compounds, all of which share this same arrangement of atoms. One of the most common and well-known compounds with this formula is acetanilide. Acetanilide is an organic compound that was historically used as an analgesic and antipyretic, though its use has largely been superseded by safer alternatives like acetaminophen. It is a white, crystalline solid that is soluble in hot water and ethanol. Acetanilide can be synthesized by the acetylation of aniline.

Another isomer of C12H11NO is p-aminoacetophenone. This compound is a solid at room temperature and is sometimes used as an intermediate in the synthesis of other organic molecules. It contains both an amine group and a ketone group attached to a benzene ring.

Other possible isomers of C12H11NO include various substituted anilines and acetophenones, as well as other less common structural arrangements. The specific properties and applications of a compound with the formula C12H11NO depend entirely on how the atoms are connected, meaning its specific isomer. Determining the exact compound requires further information beyond just the molecular formula.
