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]
CH 3 CH 2 OH + H 2 SO 4 → CH 3 CH 2 OSO 3 H + H 2 O. If the temperature exceeds 140 °C, the ethyl sulfate product tends to react with residual ethanol starting material, producing diethyl ether. If the temperature exceeds 170 °C in a considerable excess of sulfuric acid, the ethyl sulfate breaks down into ethylene and sulfuric acid. [12] [13]
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.
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 ...
(2-[(4-Aminophenyl)sulfonyl]ethyl hydrogen sulfate) Possible variations result from further substituents on the aromatic ring - usually hydroxy, methyl or methoxy groups - or from the position of the amino relative to the vinyl sulfone group. In addition to the para-substituted compound, also meta- and orthosubstituted vinyl sulfone anilines ...
Tris(2-aminoethyl)amine is the organic compound with the formula N(CH 2 CH 2 NH 2) 3. This colourless liquid is soluble in water and is highly basic, consisting of a tertiary amine center and three pendant primary amine groups. Tris(2-aminoethyl)amine is commonly abbreviated as tren or TREN.
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.
Hydroxylamine-O-sulfonic acid (HOSA) or aminosulfuric acid is the inorganic compound with molecular formula H 3 NO 4 S that is formed by the sulfonation of hydroxylamine with oleum. [2] It is a white, water-soluble and hygroscopic , solid, commonly represented by the condensed structural formula H 2 NOSO 3 H, though it actually exists as a ...
