Overview

2-hydroxyethyl prop-2-enoate (CAS 818-61-1) is an acrylic ester monomer with reactive vinyl functionality and hydroxyl groups enabling diverse polymerization applications. This versatile chemical compound, also known by its IUPAC designation, represents an important class of hydroxyl-functional acrylic monomers widely utilized in industrial polymer chemistry. With a molecular formula of C5H8O3 and molecular weight of 116.11 g/mol, this substance combines the reactivity of acrylic double bonds with the functionality of hydroxyl groups, making it particularly valuable for crosslinking applications and the synthesis of functional polymers. The compound presents significant safety considerations requiring careful handling protocols. Classified under multiple hazard categories including Acute Toxicity 3, Skin Corrosion 1B, and Skin Sensitization 1, it demands appropriate personal protective equipment and controlled storage conditions. The GHS pictograms GHS06, GHS05, and GHS09 indicate its corrosive nature, toxicity, and environmental hazard potential. Transportation falls under ADR Class 8, reflecting its corrosive properties. Industrial applications primarily focus on polymer and coating formulations where hydroxyl functionality is essential. The compound serves as a key monomer in the production of functional acrylic polymers, crosslinked coating systems, and adhesive formulations. Its dual functionality enables the creation of polymers with pendant hydroxyl groups, facilitating subsequent chemical modifications or crosslinking reactions. Unlike simpler compounds such as pentanedial, this acrylic monomer offers the advantage of vinyl polymerization combined with hydroxyl reactivity. The coating industry particularly values this monomer for producing environmentally compliant, low-VOC formulations where hydroxyl groups enable crosslinking with isocyanates or amino resins. OYSI maintains reliable supply channels for 2-hydroxyethyl prop-2-enoate to support European industrial customers' technical polymer applications.
