An amyl alcohol is any of eight alcohols with the formula C5 H12 O.[1] 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 important products. The name amyl alcohol without further specification applies to the normal (straight-chain) form, 1-pentanol .[2]
These are the 8 alcohols that are structural isomers with molecular formula C5 H12 O:

2-pentanol or sec -amyl alcohol or methyl (n) propyl carbinol
secondary
Pentan-2-ol
118.8
3-methyl-2-butanol or sec -isoamyl alcohol or methyl isopropyl carbinol
secondary
3-Methylbutan-2-ol
113.6
3-Pentanol
secondary
Pentan-3-ol
115.3
2-methyl-2-butanol or tert -amyl alcohol
tertiary
2-Methylbutan-2-ol

Three of these alcohols, 2-methyl-1-butanol, 2-pentanol, and 3-methyl-2-butanol (methyl isopropyl carbinol), are therefore 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.
