Butylone contains a methyl substitution at RN, a substitution which is shared with MDEA, ethylone, four-MEC, and particular other stimulants and entactogens. Moreover, butylone includes substitutions at R3 and R4 in the phenyl ring with oxygen teams. These oxygen groups are integrated into a methylenedioxy ring via a methylene chain. https://ernestf962hia8.wikikali.com/user
