BDPC (systematic name 4-(4-bromophenyl)-4-(dimethylamino)-1-(2-phenylethyl)cyclohexanol; also known as bromadol) is a potent fully synthetic opioid with a distinctive arylcyclohexylamine chemical structure.

[1] Initial studies estimated that it was around 10,000 times the potency of morphine in animal models.

[2] However, later studies using more modern techniques assigned a value of 504 times the potency of morphine for the more active trans-isomer.

[3] This drug was first seized along with three kilograms of acetylfentanyl in an April 25, 2013 police action in Montreal, Canada,[4] and has reportedly continued to be available on the designer drug market internationally.

[5][6] Analogues where the para-bromine is replaced by chlorine or a methyl group retain similar activity, while the meta-hydroxyl derivative demonstrated robust antagonist activity.
