3,4-Dimethoxyphenethylamine Chemical Properties,Usage,Production

Chemical Properties

3,4-Dimethoxyphenethylamine is clear yellowish oil

Uses

3,4-Dimethoxyphenethylamine is a methylated metabolite of Dopamine (D533780); a potent inhibitor of brain mitochondrial respiration used in Parkinson’s disease studies.

Uses

A methylated metabolite of Dopamine (D533780); a potent inhibitor of brain mitochondrial respiration used in Parkinson’s disease studies.

Uses

Precursor for the synthesis of isoquinolines.

Definition

ChEBI: An aromatic ether that is the derivative of 2-phenylethylamine with methoxy substituents at the 3- and 4-positions. It is an alkaloid isolated from the Cactaceae family.

Flammability and Explosibility

Not classified

Safety Profile

Poison by intravenous and intraperitoneal routes. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

Purify the amine by fractionation through an efficient column in an inert atmosphere as it is a relatively strong base. [Horner & Sturm Justus Liebigs Ann Chem 608 12819 1957, Jung et al. J Am Chem Soc 75 4664 1953.] The hydrochloride has m 152o, 154o, 156o (from EtOH, Me2CO or EtOH/Et2O), the picrate has m 165-167o(dec), and the 4-nitrobenzoyl derivative has m 147o [Buck J Am Chem Soc 55 2593 1933].
