Overview

Tert-butyl prop-2-enoate (CAS 1663-39-4) is an acrylic ester monomer with reactive vinyl functionality and enhanced thermal stability from its bulky tert-butyl group. This specialized acrylic monomer represents an important building block in polymer chemistry, combining the reactivity of acrylic acid derivatives with the steric properties of tertiary butyl substituents. The compound's molecular structure features a prop-2-enoate backbone with a tert-butyl ester group, providing unique polymerization characteristics that distinguish it from conventional acrylates. With its molecular formula C7H12O2 and molecular weight of 128.17 g/mol, tert-butyl prop-2-enoate exhibits properties that make it valuable for creating polymers with specific thermal and mechanical properties. The substance is classified as a flammable liquid requiring careful handling protocols due to its Class 3 ADR classification and associated safety hazards including acute toxicity and skin sensitization potential. Its vapor can form explosive mixtures with air, necessitating appropriate fire prevention measures and proper ventilation systems during processing. Like other acrylic compounds in this chemical family, including ethyl N-(2-methylpropoxycarbothioyl)carbamate, proper personal protective equipment and engineering controls are essential for safe handling. Primary industrial applications include specialty polymer synthesis, where the tert-butyl group provides enhanced thermal stability and altered glass transition temperatures in the resulting polymers. The monomer is particularly valuable in producing high-performance coatings and adhesives where temperature resistance is critical. Additionally, it serves as a reactive intermediate in pharmaceutical synthesis and specialty chemical manufacturing, where its unique steric properties enable selective chemical transformations. OYSI maintains reliable supplies of tert-butyl prop-2-enoate for European industrial customers, ensuring consistent quality and regulatory compliance for demanding applications.
