2CB-2-EtO, also known as 4-bromo-2-methoxy-5-ethoxyphenethylamine, is a psychedelic drug of the phenethylamine, 2C, and TWEETIO families related to 2C-B. [1] [2] [3] [4] It is the derivative of 2C-B in which the methoxy group at the 2 position has been replaced with an ethoxy group. [1] [2] [3] [4] According to Alexander Shulgin in his book PiHKAL (Phenethylamines I Have Known and Loved) and other publications, 2CB-2-ETO produces maximal effects at a dose of about 15 mg orally. [1] [3] [4] Higher doses of 30 to 50 mg orally did not increase its effects any further but only prolonged their duration, from about 3 hours to perhaps 6 hours. [1] [3] [4] 2CB-2-ETO was said to have not had an intensity that resembled that of 2C-B at any dose. [1] It was also said to be dramatically or about 5-fold less potent than 2C-B. [2] The chemical synthesis of 2CB-2-ETO has been described. [1] The drug was first described in the literature by Shulgin in PiHKAL in 1991. [1] It was developed and tested by Darrell Lemaire, with publication via personal communication with Shulgin. [3] [5] [6] [7] [8]

"There are two “Tweetios” known that are related to 2C-B. (See recipe #23 for the origin of this phrase.) The 2-EtO- homologue of 2C-B is 4-bromo-2-ethoxy-5-methoxyphenethylamine, or 2CB-2ETO. The unbrominated benzaldehyde (2-ethoxy-5-methoxybenzaldehyde) had a melting point of 47.5–48.5 °C, the unbrominated nitrostyrene intermediate a melting point of 76–77 °C, and the final hydrochloride a melting point of 185–186 °C. The hydrobromide salt had a melting point of 168.5–169.5 °C. It seems that one gets about as much effect as can be had, with a dosage of about 15 milligrams, and increases above this, to 30 and to 50 milligrams merely prolong the activity (from about 3 hours to perhaps 6 hours). At no dose was there an intensity that in any way resembled that of 2C-B."

The two tweetio analogs (2-ethoxy and 5-ethoxy) of both 2C-D and 2C-B have been explored and have dramatically reduced activity. The 5-tweetio (5-ethoxy) compounds are of twofold lessened potency, and the 2-tweetio (2-ethoxy) materials are down by another factor of five. The bis-etios (2,5-diethoxy homologs of 2C-D and 2C-B) are not known to be active at all.
