6-Methyl-MDA, also known as 6-methyl-3,4-methylenedioxyamphetamine is an entactogen and psychedelic drug of the amphetamine and MDxx families. It was first synthesized in the late 1990s by a team including David E. Nichols at Purdue University while investigating derivatives of 3,4-methylenedioxyamphetamine (MDA) and 3,4-methylenedioxy-N-methylamphetamine (MDMA).

2C-YN is an analog of phenethylamine that can be synthesized from 2C-I. Very little data exists about the pharmacological properties, metabolism, and toxicity of 2C-YN, although Daniel Trachsel lists it as having a dosage of around 50mg and a duration of around 2 hours, with relatively mild psychedelic effects.
