3-Methylbutan-1-ol

An organic compound used in the production of flavors and fragrances

3-Methylbutan-1-ol, also known as isoamyl alcohol or isopentyl alcohol, is an organic compound with the chemical formula C₅H₁₂O. It is one of several isomers of amyl alcohol.

Structure and Properties

3-Methylbutan-1-ol is a primary alcohol with a branched chain structure. The molecule consists of a five-carbon chain with a hydroxyl group (-OH) attached to the terminal carbon. The presence of the methyl group on the third carbon distinguishes it from other isomers of amyl alcohol.

The compound is a colorless liquid with a characteristic strong odor. It has a boiling point of 131°C and a melting point of -117°C. Its density is 0.810 g/cm³, making it less dense than water.

Production

3-Methylbutan-1-ol is typically produced by the fermentation of carbohydrates. It can also be synthesized through the hydroformylation of isobutene followed by hydrogenation.

Applications

3-Methylbutan-1-ol is used in the production of esters such as isoamyl acetate, which is used as a flavoring agent in the food industry. It is also used in the manufacture of fragrances and as a solvent in various industrial applications.

Safety and Handling

3-Methylbutan-1-ol is flammable and should be handled with care. It can cause irritation to the skin and eyes, and inhalation of its vapors can lead to respiratory irritation. Proper personal protective equipment (PPE) should be used when handling this chemical.
