Hydroquinone monomethyl ether (mequinol, 4-methoxyphenol) has a faint sweet-phenolic, slightly anisic and medicinal odor with a woody-guaiacol undertone. In perfumery it is primarily used as an antioxidant/stabilizer rather than as an odorant, so its scent contribution in-formula is usually negligible.AI · claude-opus-4-7
