3,5-DMA (3,5-Dimethoxyamphetamine) hydrochloride is an alkylphenylamine compound primarily catalyzed by NAT2. The metabolic rate of 3,5-DMA hydrochloride is closely related to the NAT2 acetylator genotype variation. 3,5-DMA is useful for studying the role of NAT2 acetylator genotype variation in the metabolism of alkylphenylamine carcinogens.
