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]
2-Methyl-3-pentanol (IUPAC name: 2-methylpentan-3-ol) is an organic chemical compound. It is a secondary alcohol [2] that is used as a fuel. [3] References

solution forms oily layer in 3–5 minutes: secondary, such as 2-pentanol; solution forms an oily layer immediately: tertiary, such as 2-methyl-2-butanol; The Lucas test is usually an alternative to the oxidation test - which is used to identify primary and secondary alcohols.
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 ]
