Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C 4 H 9 O H, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; [1] all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, sec-BuOH, i-BuOH, and t-BuOH).
This unsaturated aldehyde is then partially hydrogenated to form 2-ethylhexanal, a precursor to plasticizers such as bis(2-ethylhexyl) phthalate. [ 4 ] Butyraldehyde is a component in the two-step synthesis of trimethylolpropane , which is used for the production of alkyd resins .
4-Hydroxy-5-methoxytryptamine (4-HO-5-MeO-T) is a serotonergic neurotoxin of the tryptamine family. [1] [2] It is structurally related to the monoamine neurotransmitter serotonin (5-hydroxytryptamine; 5-HT). [2] [1] The drug is also a monoamine reuptake inhibitor. [2] [1] Its analogue 4,5-dihydroxytryptamine (4,5-DHT) is also a serotonergic ...
In organic chemistry, 3-hydroxybutanal (acetaldol, aldol) is an organic compound with the formula CH 3 CH(OH)CH 2 CHO and the structure H 3 C−CH−CH 2 −CH=O. It is classified as an aldol ( R−CH(OH)−CHR'−C(=O)−R" ) and the word "aldol" can refer specifically to 3-hydroxybutanal.
Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate is a high molecular weight additive, with low volatility. It is well suited to stabilising polyolefins against degradation caused by long term heat aging. [1] It is an approved food contact material in the US. [2]
The dehydrogenation of 2-butanol is catalysed by copper, zinc, or bronze: CH 3 CH(OH)CH 2 CH 3 → CH 3 C(O)CH 2 CH 3 + H 2. This is used to produce approximately 700 million kilograms yearly. Other syntheses that have been examined but not implemented include Wacker oxidation of 2-butene and oxidation of isobutylbenzene, which is analogous to ...
[2] [3] [4] They are also listed in the documents that are part of the 1998 Tobacco Master Settlement Agreement. [5] It applies, as documented, only to American manufactured cigarettes intended for distribution within the United States by the listed companies.
Recently, analogs of GHB, such as 4-hydroxy-4-methylpentanoic acid (UMB68) have been synthesised and tested on animals, in order to gain a better understanding of GHB's mode of action. [114] Analogues of GHB such as 3-methyl-GHB, 4-methyl-GHB , and 4-phenyl-GHB have been shown to produce similar effects to GHB in some animal studies, but these ...
