1-(5-bromo-2,4-dimethoxyphenyl)propan-2-amine

Meta-DOB, or 5-bromo-2,4-dimethoxyamphetamine, is a lesser-known psychedelic drug. It is similar in structure to DOB. Meta-DOB was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage range is listed as 50–100mg, and the duration listed as 5–6 hours. Meta-DOB produces few to no effects. Very little data exists about the pharmacological properties, metabolism, and toxicity of Meta-DOB.
