2,5-Dimethoxybenzaldehyde Chemical Properties,Usage,Production
Chemical Properties
yellow crystalline solid
Uses
2,5-Dimethoxybenzaldehyde is used in the preparation of 2,5-dimethoxyphenethylamine, which is utilized to prepare psychoactive drugs such as 2,5-dimethoxy-4-bromophenethylamine, 2,5-dimethoxy-4-iodophenethylamine and 4-Chloro-2,5-dimethoxy-phenethylamine. It acts as an intermediate in organic synthesis.
Application
2,5-Dimethoxybenzaldehyde, also known as 2C-H, is an organic compound and a benzaldehyde derivative. It can be used to produce 2,5-dimethoxyphenethylamine. 2C-H is also used to produce many other substituted phenethylamines such as 2C-B, 2C-I and 2C-C.
Definition
ChEBI: 2,5-dimethoxy-Benzaldehyde is a dimethoxybenzene.
Preparation
2,5-Dimethoxybenzaldehyde synthesis: Anethole is oxidized to anisaldehyde , which after isolation is subjected to a BaeyerVilliger oxidation reaction with performic or peracetic acid. The O-formyl-4-methoxyphenol obtained this way is hydrolyzed . 4-Methoxyphenol is subsequently formylated using the Reimer-Tiemann method and the obtained 2-hydroxy-5-methoxybenzaldehyde is methylated with dimethylsulfate to 2,5-dimethoxybenzaldehyde.
Synthesis
The synthesis of 2,5-dimethoxybenzaldehyde (2,5-DMBA) is mainly achieved through several well-established chemical methods, typically using readily available precursors as starting materials. A common industrial method is the formylation of 1,4-dimethoxybenzene (hydroquinone dimethyl ether), usually using the Vilsmeier-Haack reaction with reagents including N,N-dimethylformamide and phosphorus oxychloride; or using a Friedel-Crafts-type reaction, starting with 1,1-dichlorodimethyl ether, directly introducing the aldehyde group onto the activated aromatic ring. In addition, 2,5-DMBA can also be prepared by oxidizing the methyl group of 2,5-dimethoxytoluene, or through a multi-step reaction, starting with p-methoxyphenol, first undergoing a Reimer-Tiemann reaction to generate 2-hydroxy-5-methoxybenzaldehyde, and finally methoxylating it with dimethyl sulfate. These methods offer flexibility in terms of scale and precursor availability, making 2,5-DMBA a versatile intermediate for the synthesis of a wide range of fine chemicals, particularly psychoactive compounds such as 2C-H.
