应用
2-Methoxyphenol acts as an expectorant. It is used as an anti-oxidant as well as an anti-skinning agent for paints. It serves as a precursor to flavorants such as eugenol and vanillin. Further, it is used as an intermediate in the chemical synthesis of active pharmaceuticals, flavoring and perfumery products. In addition to this, it is also used as an indicator in chemical reactions that produce oxygen. 备注
