Ethanolamine-O-sulfate (EOS) is an ester of sulfuric acid and ethanolamine. EOS is a GABA transaminase inhibitor which prevents the metabolism of GABA. [2] It is used as a biochemical tool in studies involving GABA. EOS is also a diuretic [3] and an anticonvulsant. [4]
Solid sodium 2-hydroxyethyl sulfonate is a colorless, free-flowing, non-hygroscopic solid, which dissolves readily in water and has good biodegradability. Due to the method of synthesis samples often contain traces of sodium sulfite or sodium hydrogen sulfite causing aqueous solution to possesses a mildly alkaline pH of about 10. [4]
Macrocyclic polyamines analogous to crown ethers: 1,4,7-triazacyclononane ((NHCH 2 CH 2) 3) and cyclen ((NHCH 2 CH 2) 4). A related tetraaza macrocycle is cyclam. Tris(2-aminoethyl)amine (N(CH 2 CH 2 NH 2) 3) is a branched polyamine that is a minor side product of the polyethyleneamine process. A related tripodal polyamine is 1,1,1-tris ...
Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2. The pure free base is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air oxidation. It is soluble in polar solvents.
Ethanolamine (2-aminoethanol, monoethanolamine, ETA, or MEA) is a naturally occurring organic chemical compound with the formula HOCH 2 CH 2 NH 2 or C 2 H 7 NO. [8] The molecule is bifunctional, containing both a primary amine and a primary alcohol. Ethanolamine is a colorless, viscous liquid with an odor reminiscent of ammonia. [9]
The commercial production of amino acids usually relies on mutant bacteria that overproduce individual amino acids using glucose as a carbon source. Some amino acids are produced by enzymatic conversions of synthetic intermediates. 2-Aminothiazoline-4-carboxylic acid is an intermediate in the industrial synthesis of L-cysteine for example.
Ethyl sulfate can be produced in a laboratory setting by reacting ethanol with sulfuric acid under a gentle boil, while keeping the reaction below 140 °C. The sulfuric acid must be added dropwise or the reaction must be actively cooled because the reaction itself is highly exothermic. CH 3 CH 2 OH + H 2 SO 4 → CH 3 CH 2 OSO 3 H + H 2 O
The general formula is R−SO 2 NR'R" or R−S(=O) 2 −NR'R", where each R is some organic group; for example, "methanesulfonamide" (where R = methane, R' = R" = hydrogen) is CH 3 SO 2 NH 2. Any sulfonamide can be considered as derived from a sulfonic acid by replacing a hydroxyl group (−OH) with an amine group.
