Anisole, or methoxybenzene, is an organic compound with the formula CH3OC6H5. It is a colorless liquid with a smell reminiscent of anise seed, and in fact many of its derivatives are found in natural and artificial fragrances. The compound is mainly made synthetically and is a precursor to other synthetic compounds. Structurally, it is an ether (−O−) with a methyl (−CH3) and phenyl (−C6H5) group attached. Anisole is a standard reagent of both practical and pedagogical value.[2]

It can be prepared by the Williamson ether synthesis; sodium phenoxide is reacted with a methyl halide to yield anisole.

Anisole, C6H5−O−CH3, is the only name in the class of ethers which is retained both as a preferred IUPAC name and for use in general nomenclature. For preferred IUPAC names, no substitution is allowed; for general nomenclature substitution is allowed on the ring and on the side chain under certain conditions (see P-34.1.1.4).
