Overview

Butyl prop-2-enoate (CAS 141-32-2) is an acrylic ester monomer with polymerizable double bonds and moderate volatility. This versatile chemical compound, with molecular formula C7H12O2 and molecular weight of 128.17 g/mol, serves as a fundamental building block in polymer chemistry and industrial applications. As an acrylic ester, butyl prop-2-enoate exhibits excellent reactivity through its prop-2-enoate functional group, enabling rapid polymerization under appropriate conditions. The compound presents as a clear liquid with characteristic ester properties, offering good solubility in organic solvents while remaining relatively stable under normal storage conditions. Its four-carbon butyl chain provides optimal balance between flexibility and adhesion properties in resulting polymer structures. From a safety perspective, butyl prop-2-enoate requires careful handling due to its classification as a flammable liquid (Class 3) with skin and eye irritation potential. The compound may cause skin sensitization and specific target organ toxicity following single exposure, necessitating appropriate personal protective equipment and ventilation systems during industrial processing. Transport regulations classify it under ADR Class 3, requiring compliance with flammable liquid shipping protocols. Industrial applications primarily focus on polymer synthesis, where butyl prop-2-enoate functions as a comonomer in acrylic resin production for coatings, adhesives, and sealants. The compound finds extensive use in manufacturing pressure-sensitive adhesives and architectural coatings, where its properties complement other acrylic monomers like butyl 2-methylprop-2-enoate for enhanced performance characteristics. Additionally, it serves in specialty polymer applications requiring specific glass transition temperatures and mechanical properties. OYSI maintains reliable supply chains for butyl prop-2-enoate, supporting European industrial customers with consistent quality and technical expertise for polymer manufacturing applications.
