Mephedrone, 4-methyl methcathinone (4-MMC) or 4-methyl ephedrone, is in the category of synthetic drugs of the amphetamine and cathinone classes.  As 4-mmc is in cathinone family, it also includes phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain with an additional methyl substitution at Rα. Amphetamines and cathinones are alpha-methylated phenethylamines, cathinones holds  an additional carbonyl group at R1, an additional methyl substitutions at RN, and R4 of its phenyl ring.
