Prenol, or 3-methyl-2-buten-1-ol, is a natural alcohol. It is one of the most simple terpenoids. It is a clear colorless oil that is reasonably soluble in water and miscible with most common organic solvents. It has a fruity odor and is used occasionally in perfumery.
Isoprenol, also known as 3-methylbut-3-en-1-ol, is a hemiterpene alcohol. It is produced industrially as an intermediate to 3-methylbut-2-en-1-ol (prenol): global production in 2001 can be estimated as 6–13 thousand tons.
[2] [5] The compound is used as a reactant in the synthesis of a number of compounds. Notably it is used to synthesize 2,3-dimethylbut-2-ene, and is then converted to 2,3-dimethylbutane-2,3-diol and methyl tert-butyl ketone, better known as pinacolone. Pinacolone itself is then used in synthesis for number of pesticides.

In the similar substitution of 1-chloro-3-methyl-2-butene, the secondary 2-methyl-3-buten-2-ol is produced in a yield of 85%, while that for the primary 3-methyl-2-buten-1-ol is 15%. Allylic shifts occur because the transition state is an allyl intermediate.

2-Methyl-1-butanol (IUPAC name, also called active amyl alcohol) is an organic compound with the formula CH 3 CH 2 CH(CH 3)CH 2 OH. It is one of several isomers of amyl alcohol.This colorless liquid occurs naturally in trace amounts and has attracted some attention as a potential biofuel, exploiting its hydrophobic (gasoline-like) and branched structure.
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 ]
