1,4-Dimethoxybenzene is the para form of dimethoxybenzene, a volatile aromatic ether with a sweet floral odor. It occurs naturally in willow (Salix) and Zuchini (Cucurbita pepo). It appears to attract bees as it has a powerful response in their antenna.
Uses
Dimethoxybenzene is useful as an intermediate in synthesis of pharmaceuticals as well as other organic molecules. It is used in some paints and as a diazo dye. Cosmetically it is used on greasy skin, and with sulfur to treat acne, or as a dandruff treatment. Because of its floral odor, it is useful in perfumes and flavors. It can be used as a developer in black and white film, and as a base in synthesizing catecholamines and phenethylamines.
