n,n-dimethylphenethylamine n,n-dimethylphenethylamine n,n-dimethylphenethylamine (n,n-dmpea) is a substituted phenethylamine that is used as a flavoring agent. it is an alkaloid that was first isolated from the orchid eria jarensis. its aroma is described as "sweet, fishy". it is mainly used in cereal, cheese, dairy products, fish, fruit and meat. it is also being used in pre-workout and bodybuilding supplements with claims of a stimulant effect. n,n-dimethylphenethylamine names preferred iupac name n,n-dimethyl-2-phenylethan-1-amine other names n,n-dimethyl-2-phenylethanaminen,n-dimethyl-β-phenylethylaminen,n-dmpea identifiers cas number 1126-71-2 3d model (jsmol) interactive image chemspider 23470 echa infocard 100.156.869 pubchem cid 25125 unii i4c10u12c8 y comptox dashboard (epa) dtxsid40150114 inchi inchi=1s/c10h15n/c1-11(2)9-8-10-6-4-3-5-7-10/h3-7h,8-9h2,1-2h3key: txofscodfrherq-uhfffaoysa-n smiles cn(c)ccc1=cc=cc=c1 properties chemical formula c10h15n molar mass 149.237 g·mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). infobox references there is also evidence suggesting that n,n-dmpea acts as a taar1 agonist in humans, and as a 5-ht1a ligand in rats. some less conclusive research also indicated that it had interaction with mao-b, most likely as an enzyme substrate and not an inhibitor. n,n-dmpea is a positional isomer of methamphetamine. instead of the methyl group attached to the alpha position of phenylethylamine, it's attached to the nitrogen group. both substances have the chemical formula c10h15n. safety n,n-dmpea has been found to be safe for use as a flavoring agent by the flavor and extract manufacturers association (fema) expert panel and also by the joint expert committee on food additives (jecfa)—a collaboration between the food and agricultural organization of the united nations (fao) and the world health organization. legality in the united states, n,n-dmpea may be considered a schedule ii substance as a positional isomer of methamphetamine (c10h15n), due to the schedule ii definition of methamphetamine defined as "any quantity of methamphetamine, including its salts, isomers, and salts of isomers"
