What is 2-METHYL-AP-237 HCl Powder
2-METHYL-AP-237, chemically known as [1-2-methyl-4-(3-phenyl-2-propen-1-yl)-1-piperazinyl-1-butanone hydrochloride], is a synthetic opioid analgesic related to bucinnazine (AP-237). It contains a piperazine ring substituted with methyl and cinnamyl groups, acting as a mu-opioid receptor agonist with analgesic properties demonstrated in preclinical studies. This powder form, often offered as the hydrochloride salt, is a white crystalline solid used in pharmaceutical, forensic, and biochemical research for opioid receptor pharmacology and chemical characterization. It is strictly for research and forensic purposes and is not approved for human therapeutic or diagnostic use.
