Sveriges riksdag added TMA-2 to schedule I ("substances, plant materials and fungi which normally do not have medical use") as narcotics in Sweden as of Dec 30, 1999, published by Medical Products Agency in their regulation LVFS 2004:3 listed as 2,4,5-trimetoxiamfetamin (TMA-2).
Al 2 Me 6 reacts with aluminium trichloride to give (AlMe 2 Cl) 2. TMA/metal halide reactions have emerged as reagents in organic synthesis . Tebbe's reagent , which is used for the methylenation of esters and ketones , is prepared from TMA and titanocene dichloride . [ 9 ]
During atomic layer deposition, a film is grown on a substrate by exposing its surface to alternate gaseous species (typically referred to as precursors or reactants). In contrast to chemical vapor deposition, the precursors are never present simultaneously in the reactor, but they are inserted as a series of sequential, non-overlapping pulses.
Alexander Theodore "Sasha" Shulgin (June 17, 1925 – June 2, 2014) [1] was an American biochemist, broad researcher of synthetic psychoactive compounds, and author of works regarding these, who independently explored the organic chemistry and pharmacology of such agents—in his mid-life and later, many through preparation in his home laboratory, and testing on himself.

Trimethylamine (TMA) is an organic compound with the formula N(CH 3) 3. It is a trimethylated derivative of ammonia. TMA is widely used in industry. [5] [6] At higher concentrations it has an ammonia-like odor, and can cause necrosis of mucous membranes on contact. [7] At lower concentrations, it has a "fishy" odor, the odor associated with ...

Tetramethylammonium (TMA) is the simplest quaternary ammonium cation. It has the chemical formula [Me 4 N] + and consists of four methyl groups (−CH 3, denoted Me) attached to a central nitrogen atom. The cation is isoelectronic with neopentane (Me 4 C). It is positively-charged and can only be isolated in association with a counter-ion.
