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).
Butyraldehyde is produced almost exclusively by the hydroformylation of propylene: . CH 3 CH=CH 2 + H 2 + CO → CH 3 CH 2 CH 2 CHO. Traditionally, hydroformylation was catalyzed by cobalt carbonyl but rhodium complexes are more common.
Acetoin is a neutral, four-carbon molecule used as an external energy store by a number of fermentative bacteria. It is produced by the decarboxylation of alpha-acetolactate, a common precursor in the biosynthesis of branched-chain amino acids.
1-Butanol, also known as butan-1-ol or n-butanol, is a primary alcohol with the chemical formula C 4 H 9 OH and a linear structure. Isomers of 1-butanol are isobutanol, butan-2-ol and tert-butanol. The unmodified term butanol usually refers to the straight chain isomer.
4-Hydroxyphenylacetone is the para-hydroxy analog of phenylacetone, an inactive metabolite of amphetamine in humans. [ 1 ] [ 2 ] When it occurs as a metabolite of amphetamine, it is produced directly from the inactive metabolite phenylacetone .
4-Hydroxynonenal, or 4-hydroxy-2E-nonenal or 4-hydroxy-2-nonenal or 4-HNE or HNE, (C 9 H 16 O 2), is an α,β-unsaturated hydroxyalkenal that is produced by lipid peroxidation in cells. 4-HNE is the primary α,β-unsaturated hydroxyalkenal formed in this process. It is a colorless oil.
