Butylone contains a methyl substitution at RN, a substitution which is shared with MDEA, ethylone, four-MEC, and particular other stimulants and entactogens. Also, butylone has substitutions at R3 and R4 on the phenyl ring with oxygen groups. These oxygen groups are integrated into a methylenedioxy ring via a methylene chain. https://lordb566mjf3.bloguerosa.com/profile
