2Methylbutanol

2-Methylbutanol is a branched-chain alcohol with the chemical formula C5H12O. It is one of eight structural isomers of pentanol. Also known as active amyl alcohol or sec-amyl alcohol, it exists as a chiral molecule due to the presence of a stereocenter at the second carbon atom. This means it has two enantiomers, (R)-(-)-2-methylbutanol and (S)-(+)-2-methylbutanol.

This colorless liquid has a characteristic fruity odor and is flammable. It is slightly soluble in water but miscible with many organic solvents such as ethanol and ether. 2-Methylbutanol is produced industrially through the fractional distillation of fusel oil, a byproduct of alcoholic fermentation. It can also be synthesized through various organic chemical reactions.

In terms of applications, 2-methylbutanol serves as a solvent and an intermediate in the synthesis of other organic compounds. It is used in the production of flavors and fragrances, as well as in some pharmaceuticals and plasticizers. Its esters, such as 2-methylbutyl acetate, are also used in perfumery and as solvents. Due to its flammability and potential irritant properties, appropriate safety precautions should be taken when handling 2-methylbutanol.
