2Methyl1butanol

2-Methyl-1-butanol, also known as active amyl alcohol, is an organic compound with the chemical formula C5H12O. It is a chiral alcohol, meaning it exists as two enantiomers, (S)-2-methyl-1-butanol and (R)-2-methyl-1-butanol. These enantiomers are stereoisomers and are mirror images of each other. The compound is a colorless liquid with a characteristic fruity odor.

This alcohol is a primary alcohol, with the hydroxyl group attached to a primary carbon atom. It is slightly soluble in water but miscible with many organic solvents. 2-Methyl-1-butanol is found naturally in some fermented beverages, such as wine and beer, and is a component of fusel oil, a byproduct of alcohol fermentation. It is also produced industrially through various chemical processes.

Industrially, 2-methyl-1-butanol finds applications as a solvent, particularly for resins and oils. It is also used in the synthesis of other chemicals, including esters used as flavorings and fragrances. Due to its chiral nature, the individual enantiomers can have different properties and are sometimes used in specific applications where stereochemistry is important. The physiological effects of 2-methyl-1-butanol are similar to other alcohols, including potential central nervous system depression at higher concentrations.
