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 .
2-Methyl-2-pentanol (IUPAC name: 2-methylpentan-2-ol) is an organic chemical compound. It can be added to a gas chromatograph to help distinguish between branched compounds, especially alcohols. [2] Its presence in urine can be used to test for exposure to 2-methylpentane. [3]

Secondary alcohols react within five or so minutes (depending on their solubility). Primary alcohols do not react appreciably with Lucas reagent at room temperature. [ 3 ] Hence, the time taken for turbidity to appear is a measure of the reactivity of the class of alcohol, and this time difference is used to differentiate among the three ...
In other less formal contexts, an alcohol is often called with the name of the corresponding alkyl group followed by the word "alcohol", e.g., methyl alcohol, ethyl alcohol. Propyl alcohol may be n -propyl alcohol or isopropyl alcohol , depending on whether the hydroxyl group is bonded to the end or middle carbon on the straight propane chain.
2-Methyl-1-pentanol (IUPAC name: 2-methylpentan-1-ol) is an organic chemical compound. It's used as a solvent and an intermediate in the manufacture of other chemicals. [ 2 ] Due to its low solubility in water it has recently been suggested as a solvent in liquid–liquid extraction of ethanol from fermented feedstocks.
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 ]
Pentyl is a five-carbon alkyl group or substituent with chemical formula-C 5 H 11. It is the substituent form of the alkane pentane . In older literature, the common non-systematic name amyl was often used for the pentyl group.
