Which compound is a Schedule II precursor to amphetamine and methamphetamine?

• A. Phenylacetone (P2P, benzyl methyl ketone)
• B. Nalorphine
• C. Buprenorphine
• D. Butalbital

Answer: (A)

Understanding which chemicals can start the production of certain drugs is key here. Phenylacetone, known as P2P or benzyl methyl ketone, is a well-known starting material used to synthesize both amphetamine and methamphetamine. Through a chemical process called reductive amination with methylamine, P2P can be converted into methamphetamine, which is why it’s tightly regulated as a Schedule II precursor. The other compounds listed do not function as starting materials for making amphetamine or methamphetamine, so they don’t fit as precursors for these drugs.
