| Hazard Information | Back Directory | [Description]
1,3-Dimethoxybenzene, also known as dimethyl resorcinol or 3-methoxyanisole, belongs to the class of organic compounds known as dimethoxybenzenes. These organic aromatic compounds contain a monocyclic benzene moiety carrying two methoxy groups. 1,3-Dimethoxybenzene has been used in the synthesis of novel oxathiane spiroketal donors. It forms pi- and O-ylidic complexes with dichlorocarbene (CCl(2)).

clear colorless to slightly brown liquid | [Chemical Properties]
m-Dimethoxybenzene has a very powerful sweet-earthy, intensely, nut-like aroma. | [Occurrence]
Reported found in Gruyere de Comte, blue cheeses, filberts and cognac | [Definition]
ChEBI: 1,3-Dimethoxybenzene is a member of methoxybenzenes. | [Preparation]
From resorcinol by methylation using dimethyl sulfate and alka | [Production Methods]
1,3-Dimethoxybenzene can be produced 1) by Methylation of Resorcinol in weak
aqueous alkali with Dimethylsulfate.
2) from Methanol and Resorcinol with Potassium hydrosuIfate or Sodium naphthalene sulfonate as dehydrating agent. | [Taste threshold values]

1,3-Dimethoxybenzene can be used as a flavoring agent in the food industry. It is reported to be found in the volatiles of port wine and Roquefort cheese. | [Purification Methods]
Extract it with aqueous NaOH, and water, then dry it. Fractionally distil it from BaO or Na. [Beilstein 6 IV 5663.] |
