Product Description:

4-Penten-1-ol is a linear, unsaturated primary alcohol featuring a terminal alkene group and a hydroxyl group separated by a four-carbon chain. Its molecular formula is C5H10O, and it is a colorless to pale yellow liquid with a characteristic odor. This compound serves as a versatile building block in organic synthesis, primarily utilized for introducing a pentenyl chain or as a precursor in cross-metathesis, hydroboration, and epoxidation reactions. It is also employed as a monomer or comonomer in polymer chemistry to produce functionalized polyolefins and as a reagent in the synthesis of fine chemicals and pharmaceutical intermediates. Due to its dual functionality (alkene and alcohol), 4-Penten-1-ol is a common intermediate in academic research and industrial process development. It is typically stored under inert atmosphere to prevent oxidation and is handled with standard laboratory safety precautions.
