Isopentanol is a colorless liquid with the formula C5H12O, specifically (H3C–)2CH–CH2–CH2–OH.
Isopentanol is one of several isomers of amyl alcohol (pentanol).
Isopentanol is also known as Isoamyl alcohol, Isopentyl alcohol, or (in the IUPAC recommended nomenclature) 3-methyl-butan-1-ol.
An obsolete name for Isopentanol was isobutyl carbinol.
Isopentanol is an ingredient in the production of banana oil, an ester found in nature and also produced as a flavouring in industry.
Isopentanol is a common fusel alcohol, produced as a major by-product of ethanol fermentation.
Occurrence
Isopentanol is one of the components of the aroma of Tuber melanosporum, the black truffle.
The compound has also been identified as a chemical in the pheromone used by hornets to attract other members of the hive to attack.
Isoamyl acetate is a component of the natural aroma of bananas, especially the Gros Michel variety.
Extraction from fusel oil
Isopentanol can be separated from fusel oil by either of two methods: shaking with strong brine solution and separating the oily layer from the brine layer; distilling it and collecting the fraction that boils between 125 and 140 °C.
Further purification is possible with this procedure: shaking the product with hot limewater, separating the oily layer, drying the product with calcium chloride, and distilling it, collecting the fraction boiling between 128 and 132 °C.
Synthesis
Isopentanol can be synthesized by condensation of isobutene and formaldehyde which produces isoprenol and hydrogenation.
Isopentanol is a colourless liquid of density 0.8247 g/cm3 (0 °C), boiling at 131.6 °C, slightly soluble in water, and easily dissolved in organic solvents.
Isopentanol has a characteristic strong smell and a sharp burning taste.
Amyl alcohol has an oral LD50 of 200 mg/kg in mice, suggesting that Isopentanol is significantly more toxic than ethanol.
On passing the vapour through a red-hot tube, Isopentanol decomposes into acetylene, ethylene, propylene, and other compounds.
Isopentanol is oxidized by chromic acid to isovaleraldehyde, and Isopentanol forms addition compounds crystals with calcium chloride and tin(IV) chloride.
Uses of Isopentanol
Besides Isopentanols use in the synthesis of banana oil, Isopentanol is also an ingredient of Kovac’s reagent, used for the bacterial diagnostic indole test.
Isopentanol is also used as an antifoaming agent in the chloroform Isopentanol reagent.
Isopentanol is used in a phenol–chloroform extraction mixed with the chloroform to further inhibit RNase activity and prevent solubility of RNAs with long tracts of poly-adenine.

The mechanism of the formation of Isopentanol during alcoholic fermentation was studied by using radioactive leucine and isovaleraldehyde and determining the percentage of Isopentanol derived from these precursors.
The results partially confirm previous work in this field, but also indicate that the ultimate precursor of Isopentanol is to be found in the fermentable sugar.

Isopentanol (Isopentanol or 3-methylbutan-1-ol) that can be biologically produced is among the possible alcohols usable as an alternative fuel in internal combustion engines.
Isopentanol has a higher energy density than smaller alcohols (ca. 28.5 MJ/L, as compared to ca. 21 MJ/L for ethanol and 27 MJ/L for 1-butanol).
Isopentanol is less hydroscopic than ethanol and mixes better with hydrocarbons.
To better understand the combustion characteristics of that alcohol, new experimental data were obtained for its kinetics of oxidation in a jet-stirred reactor (JSR).
Concentration profiles of stable species were measured in a JSR at 10 atm over a range of equivalence ratios (0.35−4) and temperatures (530−1220 K).
The oxidation of Isopentanol was modeled using an extended detailed chemical kinetic reaction mechanism (2170 reactions involving 419 species) derived from a previously proposed scheme for the oxidation of a variety of fuels.
The proposed mechanism shows good agreement with the present experimental data.
Reaction path and sensitivity analyses were conducted for interpreting the results.

Isopentanol reduced growth and induced filament formation in Saccharomyces cerevisiae.
Isopentanol-induced filamentation was accompanied by an almost threefold greater increase in the specific activity of succinate dehydrogenase than in untreated cells, which suggested that Isopentanol treatment caused the cells to produce more mitochondria than in normal yeast form proliferation.
This was supported by measuring the dry weight of purified, isolated mitochondria.
Filaments have an increased chitin content which is distributed over the majority of their surface, and is not confined to bud scars and the chitin ring between mother and daughter cells as in yeast-form cells.
