Psychedelic Research Chemicals or RC Chems are new synthetic substances which are structurally similar to the original drug, while being functional analogs. Data on their effects limited due as they’re fairly new and do not have a lot of human consumption history.

Psychedelics are substances (natural or laboratory made) which cause profound changes in a one’s perceptions of reality. While under the influence of hallucinogens, users might hallcuniate visually and auditorily.

This is an Experimental Substance with little data. This is most likely because the substance is is not very old. Information is limite and incomplete.

Disclaimer: Psychedelic drugs offer some of the most powerful 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.

Description

25B-NBOH Also known as:

  • 2-({[2-(4-Brom-2,5-dimethoxyphenyl)ethyl]amino}methyl)phenol[German][ACD/IUPAC Name]
  • 2-({[2-(4-Bromo-2,5-dimethoxyphenyl)ethyl]amino}methyl)phenol[ACD/IUPAC Name]
  • 2-({[2-(4-Bromo-2,5-diméthoxyphényl)éthyl]amino}méthyl)phénol[French][ACD/IUPAC Name]
  • Phenol, 2-[[[2-(4-bromo-2,5-dimethoxyphenyl)ethyl]amino]methyl]-[ACD/Index Name]

A phenethylamine psychedelic and stimulant derivative of 2C-B, this compound is related to and has similar effects to 25b-NBOMe. It is significantly more potent than 2C-B but less potent than 25B-NBOMe. Overdoses of NBOH compounds may cause dangerous vasoconstriction. May induce uncomfortable body load.

Summary

It is a closely related analog of 25B-NBOMe and is reported to share most of its properties with the exception of a moderately reduced potency and a shorter duration. The name 25B-NBOH, which is short-hand for 2C-B-NBOH, is a derivative of the phenethylamine psychedelic 2C-B. It was first synthesized and documented in 2011 by Martin Hansen at the University of Copenhagen.

It is worth noting that compounds of the NBOH 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. Extremely little is known about the pharmacological properties, metabolism, and toxicity of 25B-NBOH in humans. It has no history of human use before being sold online as a designer drug in 2011.

It is closely related to members of the 25x-NBOMe series, which have been associated with many hospitalizations and deaths. Anecdotal reports suggest that this substance may be difficult to use safely due to its highly sensitive dose-response and unpredictable effects.

Chemistry

25B-NBOH is a substituted phenethylamine with methoxy groups CH3O- attached to carbons R2 and R5 as well as an bromine atom attached to carbon R4.

It differs from 2C-B structurally through a substitution on the amine (NH2) with a 2-hydroxybenzyl (BOH) group.

25B-NBOH shares this 2-hydroxybenzyl substitution with other chemicals of the NBOH family.

This NBOH addition is comprised of a hydroxy ether OH- bound to a benzene ring at R2.

Legal Status

  • Brazil: As of December 10, 2018, 25B-NBOH has been added to Portaria SVS/MS nº 344. Possession, distribution and use of this substance is now considered illegal.
  • Germany: 25B-NBOH is controlled under the NpSG (New Psychoactive Substances Act) as of November 26, 2016. Production and import with the aim to place it on the market, administration to another person and trading is punishable. Possession is illegal but not penalized.
  • Sweden: The Riksdag added 25B-NBOH to Narcotic Drugs Punishments Act under swedish schedule I ("substances, plant materials and fungi which normally do not have medical use") as of August 18, 2015, published by Medical Products Agency (MPA) in regulation HSLF-FS 2015:12
  • United Kingdom: 25B-NBOH is a Class A drug in the United Kingdom as a result of the N-benzylphenethylamine catch-all clause.
  • United States: 25B-NBOH is not a controlled substance in the United States but possession or distribution for human use could potentially be prosecuted under the Federal Analogue Act due to its structural and pharmacological similarities to 25B-NBOMe.
