This chemical is phenethylamine's beta-ketone analogue and also goes by the longer name 2-amino-1-(4-bromo-2,5-dimethoxyphenyl)ethanone. BK-2C-B is known to have psychedelic effects and is related to 2C-B on a structural level. 2C-B has been difficult for many researchers to get their hands on for the last three decades because of very strict licensing and regulatory requirements on it and similar compounds. At this point though, no license is needed for researching this particular form of 2C-B in most areas. It is up to researchers to know the laws pertaining to these compounds in their region, however.
