4-HYDROXYAMPHETAMINE

3-hydroxylation of methamphetamine and its metabolites does not generally occur, and neither does deamination to 1-phenyl-2-propanone.

In a urine sample taken 24 hours after the ingestion of methamphetamine, about 1% will consist of 4-OH-methamphetamine, about 50% unchanged methamphetamine, and with the rest consisting of benzoic acid. The other metabolites shown above are minor.
