2-Methyl-1-butanol, identified by CAS number 137-32-6, is a branched-chain primary alcohol also known as active amyl alcohol. It is a colorless liquid characterized by a distinct, somewhat pungent odor and is naturally occurring in various fruits and fermented beverages. As a chiral compound, it exists as a racemic mixture in most industrial applications, offering unique chemical properties compared to its linear isomer, n-pentanol. Its molecular structure features a methyl group on the second carbon, which influences its boiling point, solubility, and reactivity in organic synthesis.
In industrial and research settings, this chemical is valued for its versatility as both a solvent and a chemical intermediate. It exhibits moderate volatility and is miscible with most organic solvents, though it has limited solubility in water. Due to its flammable nature and potential for irritation, handling requires standard safety protocols, including adequate ventilation and protective equipment. Its stability under normal conditions makes it a reliable building block for producing a wide array of derivatives used in specialty chemicals and consumer products.
