Used as a key intermediate in the synthesis of psychoactive substances, particularly in the production of certain hallucinogenic compounds like TMA-2 (2,4,5-trimethoxyamphetamine). It serves as a precursor in clandestine pharmaceutical chemistry due to its structural similarity to amphetamine derivatives. Also finds limited use in research settings for studying serotonin receptor activity and neurochemical pathways. Its application is highly regulated due to potential misuse in illegal drug manufacturing.
