Amyl alcohol \Am"yl al"co*hol\ (Org. Chem.)
   Any of eight isomeric liquid alcohols ({C5H11.OH}),
   transparent, colorless liquids. It is the hydroxide of amyl.
   Also called {amylic alcohol}. The amyl alcohol obtained from
   {fusel oil} is mostly isoamyl alcohol (3-methyl-1-butanol or
   1-hydroxy-3-methylbutane), with some {sec-amyl alcohol}
   (2-methyl-1-butanol or {2-pentanol}), and has a
   characteristic peculiar odor. Other than {n-amyl alcohol}
   (also called {1-pentanol}) the other isomeric pentanols are
   not usually refered to as amyl alcohol. The amyl alcohol
   mixture in fusel oil forms a colorless liquid with a peculiar
   cough-exciting odor and burning taste. It is used as a source
   of amyl compounds, such as amyl acetate, amyl nitrite, etc.
