CT-4719, also known as 2,4-dichloro-5-methoxyphenoxyethylamine, is a claimed hallucinogen related to psychedelic phenethylamines like mescaline. It is not technically a phenethylamine itself but is a close analogue of this family. The drug was reported to produce behavioral and electrocorticography (ECoG) effects very similar to but twice as potent as those of mescaline in cats. CT-4719 was first described in the scientific literature by 1969. Various related analogues, such as CT-5172 and CT-5126, have also been described. CT-4719 and related compounds were developed at the Laboratoire de Chimie Thérapeutique (CT; Therapeutic Chemistry Laboratory) of the Pasteur Institute in Paris, France.

An analogue of CT-4719 and of mescaline, 3,4,5-trimethoxyphenoxyethylamine, has also been described. It was inactive in terms of psychoactive effects in humans at doses of 10 to 300 mg.
