βk-2C-B(also known as Bk-2C-B, or beta-keto 2C-B) is a novel psychedelic substance of the phenethylamine class. It is a structural analog of 2C-B.bk-2c-b vs 2c-b,2c-b-fly vendor,2c-b-fly for sale,2c-b psychonaut
Subjective effects include open and closed-eye visuals, time distortion, euphoria, and ego loss. Compared to 2C-B, its effects are often described as being considerably more stimulating and less psychedelic with a significantly longer duration.
Bk-2C-B is relatively uncommon and has little to no history of human usage prior to its 2014 distribution by online vendors as a research chemical.
Very little data exists about the pharmacological properties, metabolism, and toxicity of Bk-2C-B. As a result, users are advised to approach this novel and poorly understood hallucinogenic substance with the proper amount of precaution and harm reduction practices if choosing to use it.
The original synthesis of βk-2C-B is not available on the public record. However, based on information gathered from internet forums and scientific studies, it appears that it was not originally synthesized in the 1970s by Alexander Shulgin like many 2C-x compounds.
The first reliable mention of ?k-2C-B does not appear until 2004, with it playing only a minor role in a scientific study as a precursor of 5-HT2A serotonin receptor agonists.bk-2c-b vs 2c-b,2c-b-fly vendor,2c-b-fly for sale,2c-b psychonaut
The next confirmed mention of the substance can be dated to December 2007. At that time, the user “King Kong” of the bluelight.org forum opened a thread for information and discussion of bk-2c-b,βk-2C-B.
There was a brief discussion about the possible instability of the molecule, but not more than 20 posts were written in the following 6 years.
βk-2C-B received more attention since 2013 when the first experience reports appear on the internet following its appearance on the research chemical market via “online head shops” start selling it as “a legal replacement for 2C-B”.
Overall, βk-2C-B is considered a relatively obscure substance, even among research chemicals.
An analysis of the Google search history between 2013-2017 shows that 2C-B was consistently searched 3-4 times more often βk-2C-B. Since 2017, βk-2C-B seems to have almost completely disappeared from the open market.
βk-2C-B, or beta-keto 2C-B, is a substituted phenethylamine featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain. ?k-2C-B contains the structure of 2C-B substituted with a ketone group at the beta carbon of the structure (R1). 2-A1MP
?k-2C-B contains methoxy functional groups CH3O- attached to carbons R2 and R5 as well as a bromine atom attached to carbon R4 of the phenyl ring. 4-meo-pv9
?k-2C-B belongs to the 2C family of phenethylamines which contain methoxy groups on the 2 and 5 positions of the benzene ring.2C-B-FLY
