N-Benzyl-2C-B (25B-NB, NB-2C-B) is a recreational designer drug from the 25-NB subgroup of the substituted phenethylamine family, with psychedelic effects. It has a binding affinity (K i ) of 16 nM at the serotonin receptor 5-HT 2A and 90 nM at 5-HT 2C and reportedly has a potency in between that of 2C-B and NBOMe-2C-B .
The 25-NB (25x-NBx) series, or NBOMe series, also known as the N-benzylphenethylamines, is a family of serotonergic psychedelics. [ 1 ] [ 2 ] They are substituted phenethylamines and were derived from the 2C family . [ 2 ]
The N-benzyl derivative however was found to have higher binding affinity than 2C-B itself, with N-(4-bromobenzyl)-2CB binding even more tightly. [49] This initial research did not include functional assays of activity, but later led to the development of potent substituted N-benzyl derivatives such as 25B-NBOMe, [50] and 25B-NBOH.
Like other 2C-X-NBOMe molecules, 25I-NBOMe is a derivative of the 2C family of phenethylamines described by chemist Alexander Shulgin in his book PiHKAL. [ 17 ] [ 15 ] Specifically, 25I-NBOMe is an N -benzyl derivative of the phenethylamine molecule 2C-I , formed by adding a 2-methoxybenzyl (BnOMe) onto the nitrogen (N) of the phenethylamine ...
Together with the benzyltriethylammonium salt, benzyltrimethylammonium hydroxide is a popular phase-transfer catalyst. [2]It is used in aldol condensation reactions and base-catalyzed dehydration reactions.
2C-B-BZP contains a benzylpiperazine base as well as the ring-substitution pattern of the psychedelic phenethylamine 2C-B. 2C-B-BZP is not a phenethylamine itself and does not produce psychedelic effects, as the binding groups are in the wrong position to activate the 5-HT 2A receptor, while the phenylpiperazine homologue 2C-B-PP substitutes for DOM in DOM-trained rats with around one-tenth ...
Benzylamine is used as a masked source of ammonia, since after N-alkylation, the benzyl group can be removed by hydrogenolysis: [10] C 6 H 5 CH 2 NH 2 + 2 RBr → C 6 H 5 CH 2 NR 2 + 2 HBr C 6 H 5 CH 2 NR 2 + H 2 → C 6 H 5 CH 3 + R 2 NH. Typically a base is employed in the first step to absorb the HBr (or related acid for other kinds of ...
N-Ethyl-2C-B is a recreational designer drug with psychedelic effects. [1] It was first synthesised in the 1990s, [2] and was first identified as a new psychoactive substance in Finland in 2007. [3] It is specifically listed as an illegal drug in Finland, [4] and controlled under analogue provisions in a number of other jurisdictions.
