Overview

Tert-butyl prop-2-enoate (CAS 1663-39-4) is an acrylate ester monomer with flammable properties and significant industrial polymerization applications. This versatile chemical compound, also known by its IUPAC name tert-butyl prop-2-enoate, represents an important member of the acrylate ester family used extensively in polymer chemistry and industrial manufacturing. With the molecular formula C7H12O2 and a molecular weight of 128.17 g/mol, this colorless liquid demonstrates the characteristic reactivity of acrylic monomers while offering unique properties due to its bulky tert-butyl group. The compound is classified under multiple hazard categories, requiring careful handling protocols in industrial environments. As a Category 2 flammable liquid (ADR Class 3), it presents fire risks and must be stored away from ignition sources. The substance exhibits acute toxicity properties and can cause skin irritation and sensitization, necessitating appropriate personal protective equipment during handling and processing. The GHS classification includes pictograms GHS02, GHS07, and GHS09, reflecting its flammable nature and health hazards. Tert-butyl prop-2-enoate finds primary application in the production of specialized acrylic polymers and copolymers, where the tert-butyl group provides enhanced thermal stability and unique solubility characteristics. It serves as a valuable monomer in coatings formulations, adhesive systems, and specialty plastic manufacturing. The compound is also utilized in the synthesis of functional polymers for advanced materials applications, often in combination with other acrylate derivatives. Like other acrylate compounds such as ethyl N-(2-methylpropoxycarbothioyl)carbamate, proper polymerization inhibition during storage and transport is essential to maintain product stability and prevent unwanted reactions. OYSI supplies tert-butyl prop-2-enoate to meet diverse industrial requirements across European markets.
