4-Methylpentedrone
4-Methylpentedrone, is a stimulant medication of the cathinone class, invented in 1960.
It is a higher homolog of 4-methylmethcathinone and 4-methylbuphedrone, and the p-methyl derivative of pentedrone. It can also be viewed as the methylamino analog of pyrovalerone.
A related compound, 4-methyl-α-ethylaminopentiophenone, has been found to be incorrectly sold as 4-methylpentedrone.
