Isoamyl alcohol is a colorless liquid with the formula C 5 H 12 O, specifically (H 3 C–) 2 CH–CH 2 –CH 2 –OH. It is one of several isomers of amyl alcohol (pentanol). It is also known as isopentyl alcohol, isopentanol, or (in the IUPAC recommended nomenclature) 3-methyl-butan-1-ol. An obsolete name for it was isobutyl carbinol. [5]
Phenol: The phenol used for biochemistry comes as a water-saturated solution with Tris buffer, as a Tris-buffered 50% phenol, 50% chloroform solution, or as a Tris-buffered 50% phenol, 48% chloroform, 2% isoamyl alcohol solution (sometimes called "25:24:1"). Phenol is naturally somewhat water-soluble, and gives a fuzzy interface, which is ...

[14] [15] A 1:1 mixture of toluene and 1,4 dioxane has δD, δP and δH values of 17.8, 1.6 and 5.5, comparable to those of chloroform at 17.8, 3.1 and 5.7 respectively. Because of the health hazards associated with toluene itself, other mixtures of solvents may be found using a full HSP dataset.
Isoamyl acetate, also known as isopentyl acetate, is an ester formed from isoamyl alcohol and acetic acid, with the molecular formula C 7 H 14 O 2. It is a colorless liquid that is only slightly soluble in water, but very soluble in most organic solvents. Isoamyl acetate has a strong odor which is described as similar to both banana and pear.

2-methyl-1-butanol - sometimes called "active" amyl alcohol; isobutyl alcohol - one of the least toxic of the butanols. 1-propanol; Other higher alcohols that can be produced during fermentation include: isopropanol (isopropyl alcohol), oxidized to form acetone by alcohol dehydrogenase in the liver, leading to ketosis when ingested in large ...
