Description

4-Hydroxybutyl acrylate (CAS No. 2478-10-6) is a high-purity, monofunctional acrylate ester with the molecular formula C₇H₁₂O₃. This versatile monomer features both a reactive acrylate group and a hydroxyl group, making it ideal for polymerization and cross-linking applications. Its IUPAC name, 4-hydroxybutyl prop-2-enoate, reflects its structural composition as an ester of acrylic acid and 1,4-butanediol. With a clear to pale yellow appearance and a characteristic mild odor, this liquid compound is widely used in UV-curable coatings, adhesives, and specialty polymers. Its hydroxyl functionality enables further chemical modifications, such as esterification or urethane formation. Packaged under inert gas to prevent premature polymerization, our 4-Hydroxybutyl acrylate is rigorously tested for purity, stability, and consistency, ensuring optimal performance in demanding research and industrial applications.
