Bis-TOM, or 2,5-TOM, also known as 4-methyl-2,5-dimethylthioamphetamine or as 2,5-dithio-DOM, is a chemical compound of the phenethylamine and amphetamine families related to DOM.[1][2] It is the analogue of DOM in which the methoxy groups at the 2 and 5 positions have been replaced with methylthio groups.[1][2]
In his book PiHKAL (Phenethylamines I Have Known and Loved) and other publications, Alexander Shulgin lists bis-TOM's dose as greater than 160 mg orally and its duration as unknown.[1][2] The effects of bis-TOM have been reported to include vague awareness of something and "a suggestion of darting, physically (when going to sleep)", but no mental effects.[1] Shulgin concluded that bis-TOM was inactive, at least at tested doses of up to 160 mg orally.[1][2] Based on the approximate 15-fold loss of potency of 2-TOM compared to DOM and the approximate 10-fold drop in potency of 5-TOM relative to DOM, Shulgin hypothesized that bis-TOM might have a potency reduction of 150-fold and might be active at a dose of around 750 mg orally.[1] However, higher doses were not tested owing in parts to hints of neurological toxicity as the potential rewards were not considered worth the risks.[1]
The chemical synthesis of bis-TOM has been described.[1] The phenethylamine (2C) analogue of bis-TOM is 2C-bis-TOM.[1] This compound was synthesized by Shulgin but was not tested in humans.[1] According to Shulgin, 2C-bis-TOM would probably not be active.[1]
Bis-TOM was first described in the scientific literature by Shulgin and Peyton Jacob III in 1983.[3] Subsequently, it was described in greater detail by Shulgin in his book PiHKAL (Phenethylamines I Have Known and Loved) in 1991.[1]
