25C-NBOMe (also known as Cimbi-36, 2C-C-NBOMe, and “N-Bomb”, although this term is used broadly to refer to the entire 25x-NBOMe family) is a novel psychedelic substance of the phenethylamine class. It produces an array of visually-dominant and stimulating psychedelic effects when administered.
The name 25C-NBOMe, which is short-hand for 2C-C-NBOMe, is a derivative of the phenethylamine psychedelic 2C-C. It was discovered in 2003 by Ralf Heim at the Free University of Berlin, and subsequently investigated by a team at Purdue University led by David Nichols. It has been studied in its radiolabelled form as a potential ligand for mapping the distribution of serotonin-2A receptors in the brain, using positron emission tomography (PET).
Users note that compounds of the NBOMe family are not orally active and should be administered sublingually by placing and holding it into one’s mouth and allowing it to absorb over a period of 15-25 minutes. 25C-NBOMe can also be vaporized and inhaled for more rapid and powerful effects and a shorter duration. However, this route of administration is highly advised against due to the difficulties of measuring and handling substances that are both active in the microgram range which highly elevates the risk of overdose.
25C-NBOMe had no history of human use before being sold online as a designer drug in 2010. Extremely little is known about the pharmacological properties, metabolism, and toxicity of 25C-NBOMe in humans, and it has been associated with many deaths and hospitalizations. Along with its highly sensitive dose-response and unpredictable effects, many reports also suggest that this substance may be overly difficult to use safely. Therefore it is highly advised to approach this poorly understood psychedelic substance with the proper amount of precaution and harm reduction practices if choosing to use it.
25C-NBOMe or 2C-C-NBOMe is a serotonergic N-benzyl derivative of the substituted phenethylamine psychedelic known as 2C-C. 25C-NBOMe is a substituted phenethylamine with methoxy groups CH3O- attached to carbons R2 and R5 as well as a chlorine atom attached to carbon R4. It differs from 2C-C structurally through a substitution on the amine (NH2) with a 2-methoxybenzyl (BOMe) group as shown in the image to the right. 25C-NBOMe shares this 2-methoxybenzyl substitution with other chemicals of the NBOMe family. This NBOMe addition contains a methoxy ether CH3O- bound to a benzene ring at R2.
