Pentan-3-ol. Other names 3-Pentanol, diethyl carbinol ... 3-Pentanol is one of the eight isomers of amyl alcohol. It is found naturally and has a role as a pheromone ...
Three of these alcohols, 2-methyl-1-butanol, 2-pentanol, and 3-methyl-2-butanol (methyl isopropyl carbinol), contain stereocenters, and are therefore chiral and optically active. The most important amyl alcohol is isoamyl alcohol , the chief one generated by fermentation in the production of alcoholic beverages and a constituent of fusel oil .
2-Pentanol (IUPAC name: pentan-2-ol; also called sec-amyl alcohol) is an organic chemical compound.It is used as a solvent and an intermediate in the manufacturing of other chemicals. 2-Pentanol is a component of many mixtures of amyl alcohols sold industrially. 2-Pentanol is chiral and thus can be obtained as either of two stereoisomers designated as (R)-(−)-2-pentanol and (S)-(+)-2-pentanol.
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.

Most other isomers of pentane-1,2,3,4,5-pentol are chiral, but xylitol has a plane of symmetry. Industrial production starts with lignocellulosic biomass from which xylan is extracted; raw biomass materials include hardwoods, softwoods, and agricultural waste from processing maize, wheat, or rice. The mixture is hydrolyzed with acid to give xylose.
In naming simple alcohols, the name of the alkane chain loses the terminal e and adds the suffix -ol, e.g., as in "ethanol" from the alkane chain name "ethane". [19] When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3.
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.
