25B-NBOMe

25B-NBOMe is a synthetic psychedelic of the substituted phenethylamine class and a member of the 25x-NBOMe series. It is an N-benzyl derivative of 2C-B, first described by Ralf Heim at the Free University of Berlin. The substance had virtually no history of human use before appearing on the research chemical market in 2010. Compared to its parent compound 2C-B, 25B-NBOMe is reported to be approximately sixteen times more potent.
