Psychoactive Research chemicals are new synthetic substances that are structurally similar to the original drug, while being functional analogs. Research on the effects of, and treatment for, abuse of these drugs is limited due to the fact that they’re fairly new and have avoided mainstream notice. Research chemicals do not have a lot of human consumption data, and thus harm-reduction and special care should be taken if choosing to ingest them.

Psychedelics are drugs which cause profound changes in a one’s perceptions of reality, otherwise known as hallucinations. While under the influence of hallucinogens, users might see images, hear sounds or feel sensations. These chemicals offer some of the most intense psychological experiences and care should be taken when ingesting them.

This is a commonly used substance with well known and widely available human consumption data. This does not guarantee that the substance will be safe. The safety profile has been established based on usage data commonly available.

Disclaimer: Psychedelic drugs offer some of the most power and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

Practice Harm Reduction. Proceed with Caution.

Description

βk-2C-B

Also known as:

  • 2-Amino-1-(4-brom-2,5-dimethoxyphenyl)ethanon[German][ACD/IUPAC Name]
  • 2-Amino-1-(4-bromo-2,5-dimethoxyphenyl)ethanone[ACD/IUPAC Name]
  • 2-Amino-1-(4-bromo-2,5-diméthoxyphényl)éthanone[French][ACD/IUPAC Name]
  • BK-2C-B
  • Ethanone, 2-amino-1-(4-bromo-2,5-dimethoxyphenyl)-[ACD/Index Name]
  • β-keto 2C-B
  • 2-?amino-?1-?(4-?bromo-?2,?5-?dimethoxyphenyl)?-Ethanone
  • 2-amine-1-(4-bromo-2,5-dimethoxyphenyl)ethanone[ACD/IUPAC Name]
  • 2-Amino-1-(4-bromo-2,5-dimethoxyphenyl)-ethanone

A long-acting psychedelic and empathogen with unpredictable effectiveness. Roughly double the duration of 2c-b. Inactivated by high pH.

Summary

It is a structural analog of 2C-B. 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.

Effects

Pharmacological Effects

Bk-2C-B likely acts as a 5-HT2A partial agonist. The psychedelic effects are believed to come from its efficacy at the 5-HT2A receptors. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.
