Norpethidine (normeperidine, pethidine intermediate B) is a 4-phenylpiperidine derivative that is both a precursor to, and the toxic metabolite of, pethidine (meperidine). It is scheduled by UN Single Convention on Narcotic Drugs. It is a Schedule II Narcotic controlled substance in the United States and has an ACSCN of 9233. The 2014 annual…

The extracted context around Norpethidine shows recurring relationship patterns in the source. For example, Norpethidine → AU: Unscheduled, BR: Class A1 (Narcotic drugs), CA: Schedule I, DE: Anlage II (Authorized trade only, not prescriptible), UN: Narcotic Schedule I, US: Schedule II Another extracted example is Norpethidine → controlled drug because of its potential uses in manufacturing both pethidine itself and a range of N-substituted derivatives, major complication when pethidine is used in medicine as an analgesic. Use these groups to spot repeated connection types before inspecting the individual relationships.
