Butylone has a methyl substitution at RN, a substitution that is shared with MDEA, ethylone, 4-MEC, and specified other stimulants and entactogens. Furthermore, butylone includes substitutions at R3 and R4 on the phenyl ring with oxygen groups. These oxygen groups are included into a methylenedioxy ring via a methylene chain. https://saulb753uwy9.newbigblog.com/profile
