C8H11NO

C8H11NO is the molecular formula for several chemical compounds, most notably N-methylaniline. N-methylaniline is an organic compound with the formula C6H5NH(CH3). It is an aniline derivative where one hydrogen atom on the nitrogen atom is replaced by a methyl group. It is a colorless to pale yellow oily liquid that turns brown on exposure to air and light. N-methylaniline is slightly soluble in water and soluble in most organic solvents. It is a weak base and is used as a precursor in the synthesis of dyes, pharmaceuticals, and agricultural chemicals. It can also be used as a solvent and as a component in some fuel additives.

Another compound with the molecular formula C8H11NO is phenylethanolamine. This compound, also known as 2-amino-1-phenylethanol, is an organic compound that contains both amine and alcohol functional groups. It can exist as two enantiomers, (R)-(-)- and (S)-(+)-phenylethanolamine, due to the chiral center at the carbon atom bearing the hydroxyl group. Phenylethanolamine is found naturally in some plants and is also synthesized for use in research and as a potential intermediate in the synthesis of other compounds.

The specific properties and applications of C8H11NO depend entirely on which isomer is being referred to. Identification of the exact compound requires knowledge of its structural formula or name.
