4Propoxyanisole

4-Propoxyanisole, also known as p-propoxyanisole, is an organic compound with the chemical formula C10H14O2. It is a derivative of anisole, where a propoxy group (-OCH2CH2CH3) is attached at the para position (position 4) of the benzene ring. Structurally, it can be considered as having an ether linkage to a benzene ring, with another ether linkage to a propyl chain.

This compound is typically encountered as a colorless liquid or a low-melting solid. It possesses a distinct aroma, often described as sweet, floral, or anise-like, which contributes to its use in perfumery and flavorings. Its physical properties, such as boiling point and solubility, are influenced by the presence of both the aromatic ring and the aliphatic propoxy chain.

4-Propoxyanisole is synthesized through various organic reactions, commonly involving the etherification of 4-methoxyphenol (hydroquinone monomethyl ether) with a propyl halide, or alternatively, the alkylation of hydroquinone with both a methyl and a propyl group. Its applications are primarily in the fragrance industry, where it serves as a component in various perfumes and colognes to impart specific olfactory notes. It may also find use as a flavoring agent in certain food products, though its regulatory status for such applications can vary by region. The compound is generally considered stable under normal storage conditions.
