6-APB, better known as Benzofury and officially as 6- (2-Aminopropyl) benzofuran, is a new entactogen of the benzofuran class. It is structurally related to MDA, MDMA, 5-APB and 5-MAPB. 6-APB
was first synthesized in 1993 by David E. Nichols as a potential non-neurotoxic alternative to MDMA. However, it did not become popular until more than ten years later before entering the research
chemicals market.
