Butylone contains a methyl substitution at RN, a substitution that's shared with MDEA, ethylone, four-MEC, and particular other stimulants and entactogens. Also, butylone consists of substitutions at R3 and R4 on the phenyl ring with oxygen teams. These oxygen teams are incorporated into a methylenedioxy ring through a methylene chain. https://masonb874nnk1.muzwiki.com/user
