2Penten1ol

2-Penten-1-ol is an organic compound with the chemical formula C5H10O. It is an unsaturated alcohol, meaning it contains both a carbon-carbon double bond and a hydroxyl group. The "2-penten" indicates a five-carbon chain with a double bond starting at the second carbon, and "-1-ol" signifies that the hydroxyl group is attached to the first carbon.

This compound exists as isomers due to the position of the double bond and the stereochemistry around it. The double bond can be in the cis (Z) or trans (E) configuration. Therefore, common forms include (Z)-2-penten-1-ol and (E)-2-penten-1-ol. It is a colorless liquid with a characteristic odor.

2-Penten-1-ol can be synthesized through various chemical reactions, often involving reduction of corresponding aldehydes or esters. It is used as a chemical intermediate in the synthesis of other organic compounds, including fragrances and flavorings, due to its reactive double bond and hydroxyl group. Its applications are typically found in specialized chemical manufacturing processes rather than in widespread consumer products.
