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 Pinalia jarensis. [1] [a] Its aroma is described as "sweet, fishy". It is mainly used in cereal, cheese, dairy products, fish, fruit and meat. [3]
lic 6 h 4 ch 2 n(ch 3) 2 + e + → 2-ec 6 h 4 ch 2 n(ch 3) 2 Via these reactions, many derivatives are known with the formula 2-X-C 6 H 4 CH 2 N(CH 3 ) 2 (E = SR, PR 2 , etc.). The amine is basic and undergoes quaternization with alkyl halides (e.g. hexyl bromide ) to give quaternary ammonium salts: [ 4 ]
The bitartrate salt of DMAE, i.e. N,N-dimethylethanolamine bitartrate, is sold as a dietary supplement. [5] It is a white powder providing 37% DMAE. [6] Animal tests show possible benefit for improving spatial memory [7] and working memory. [8]
