βk-2C-B (beta-keto 2C-B, bk-2C-B) is a psychedelic drug which is structurally related to 2C-B and BOB^[1] and has been sold online as a designer drug.^[2] It was found to be a polymorph and is prone to selfcondensation forming a dimer under basic to neutral conditions, similar to the reaction involved in pyrazine synthesis.^[3]
