  • Applications

    3-Penten-1-ol, (3E)- (CAS 764-37-4) is an allylic alcohol used as an intermediate in organic synthesis, enabling the production of allylic esters and other refined compounds. It is often regarded as a building block for polymers and functional materials, through the hydroxyl group or after conversion to esters or ethers. In the fragrance and cosmetics industries, it may be used as a fragrance ingredient or as a fragrance intermediate. In the polymer and plastics sector, it can serve as a precursor to functional monomers or derivatives for specialty polymers. In coatings and inks, it can be employed as a reactive monomer or precursor to specialized monomers. In cleaning and formulation contexts, it may act as a processing solvent or intermediate for formulation components, subject to local regulations. In pharmaceutical synthesis, it may be used as an intermediate for the preparation of more complex active compounds, depending on regulatory constraints.
