Used in the synthesis of psychoactive substances, particularly in the production of hallucinogenic phenethylamines such as TMA-2 and related compounds. It serves as a key intermediate in organic chemistry for constructing substituted amphetamines due to the reactivity of the aldehyde group and the electron-rich aromatic ring. Its methoxy substituents enhance the compound's stability and influence the pharmacological profile of the final products. Also employed in research settings for studying structure-activity relationships in psychedelic drugs. Not used in commercial pharmaceuticals or industrial applications due to its restricted nature and controlled substance precursors.
