Acetoin, also known as 3-hydroxybutanone or acetyl methyl carbinol, is an organic compound with the formula CH 3 CH(OH)C(O)CH 3. It is a colorless liquid with a pleasant, buttery odor. It is chiral. The form produced by bacteria is (R)-acetoin. [1]
Prebediolone acetate (brand names Acetoxanon, Acetoxanone, Acetoxy-Prenolon, Artisone, Artivis, Pregnartrone, Sterosone), also known as 21-hydroxypregnenolone 21-acetate or 21-acetoxypregnenolone (A.O.P.), as well as 3β,21-dihydroxypregn-5-en-20-one 21-acetate, is a synthetic pregnane steroid which is described as a glucocorticoid and has been used in the treatment of rheumatoid arthritis.
CH 3 C(O)CH 2 CO 2 H → CH 3 C(O)CH 3 + CO 2. The acid form has a half-life of 140 minutes at 37 °C in water, whereas the basic form (the anion) has a half-life of 130 hours. That is, it reacts about 55 times more slowly. [8] The corresponding decarboxylation of trifluoroacetoacetate is used to prepare trifluoroacetone: CF 3 C(O)CH 2 CO 2 H ...
The structure of the acetoxy group blue. In organic chemistry, the acetoxy group (abbr. AcO or OAc; IUPAC name: acetyloxy [1]), is a functional group with the formula −OCOCH 3 and the structure −O−C(=O)−CH 3. As the -oxy suffix implies, it differs from the acetyl group (−C(=O)−CH 3) by the presence of an additional oxygen atom.
Ethyl acetoxy butanoate (EAB) is a volatile chemical compound found as a minor component of the odour profile of ripe pineapples, though in its pure form it has a smell more similar to sour yoghurt. [1] It can be metabolized in humans into GHB, and thus can produce similar sedative effects. [citation needed]
tert-Amyl alcohol (TAA) or 2-methylbutan-2-ol (2M2B), is a branched pentanol. Historically, TAA has been used as an anesthetic [3] and more recently as a recreational drug. [4] TAA is mostly a positive allosteric modulator for GABA A receptors in the same way as ethanol. [5] The psychotropic effects of TAA and ethanol are similar, though distinct.
The reaction can also be carried out under mildly acidic conditions by way of the same intermediate using a hypervalent iodine compound in aqueous solution. [1] An example published in Organic Syntheses is the conversion of cyclobutanecarboxamide , easily synthesized from cyclobutylcarboxylic acid , to cyclobutylamine . [ 2 ]
It is used as a biochemical tool in the study of carcinogenesis. It induces tumors in a number of species in the liver, bladder and kidney. The metabolism of this compound in the body by means of biotransformation reactions is the key to its carcinogenicity . 2-AAF is a substrate for cytochrome P-450 (CYP) enzyme, which is a part of a super ...
