ZC-B
ZC-B, also known as 3-azetidine or as 2C-B-AZET, is a phenethylamine derivative which acts as a serotonin receptor agonist selective for the 5-HT2 subtypes, with an EC50 of 1.6nM at 5-HT2A, vs 5.8nM at 5-HT2C. It is structurally related to the psychedelic phenethylamines 2C-B and DOB, but with the amine side chain conformationally restricted as an azetidine ring.
