Amyl alcohol

Template:Short description Template:More refs Amyl alcohols are alcohols with the formula C₅H₁₁OH.<ref>Merriam-Webster's Collegiate Dictionary 11th Ed. 2004</ref> Eight are known. A mixture of amyl alcohols (also called amyl alcohol) can be obtained from fusel alcohol. Amyl alcohol is used as a solvent and in esterification, by which is produced amyl acetate and other products. The name amyl alcohol without further specification applies to the normal (straight-chain) form, 1-pentanol.<ref>Template:Cite book</ref>

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. The other amyl alcohols may be obtained synthetically.
