Buy Methorphan (opioid) Cas 510-53-2

Methorphan is an opioid drug that occurs in two isomeric forms, each with differing pharmacology and effects:

• Dextromethorphan – An over-the-counter cough suppressant, as well as dissociative hallucinogen.
• Levomethorphan – A potent opioid analgesic that was never clinically developed; a prodrug of the powerful opioid agonist analgesic levorphanol (Levo-Dromoran).

Racemethorphan is the racemic mixture of both of these stereoisomers.^[2] It is listed under the Single Convention on Narcotic Drugs 1961 and is therefore listed in the United States as a Controlled Substance, specifically as a Narcotic in Schedule II with an ACSCN of 9732 and an annual aggregate manufacturing quota of 3 grams in 2014.^[3][4] The salts in use are the hydrobromide (free base conversion ratio 0.770) and the tartrate (0.644).
