Overview

Hexyl prop-2-enoate (CAS 2499-95-8) is an acrylate ester monomer with polymerizable vinyl functionality and moderate skin sensitization properties. This specialized acrylate ester represents an important intermediate in polymer chemistry and industrial applications. With its molecular formula C9H16O2 and molecular weight of 156.22 g/mol, hexyl prop-2-enoate combines the reactive vinyl group characteristic of acrylate monomers with a six-carbon alkyl chain that influences both its physical properties and polymerization behavior. The compound belongs to the broader family of alkyl acrylates, sharing structural similarities with other acrylate derivatives used in coating and adhesive formulations. From a safety perspective, hexyl prop-2-enoate requires careful handling protocols due to its classification profile. The substance exhibits skin and eye irritation properties (Skin Irrit. 2, Eye Irrit. 2) and demonstrates skin sensitization potential (Skin Sens. 1), requiring appropriate personal protective equipment during industrial handling. Additionally, it presents specific target organ toxicity concerns (STOT SE 3) and chronic aquatic toxicity (Aquatic Chronic 2), necessitating controlled environmental release measures. The GHS07 and GHS09 pictograms reflect these health and environmental hazards, while its ADR Class 9 classification governs transportation requirements. Industrial applications primarily focus on polymer synthesis, specialty coatings, and adhesive formulations where the hexyl chain length provides specific performance characteristics. The compound serves as a monomer in acrylic polymer production and finds use in UV-curable systems. Related compounds such as 2-[2-(2-prop-2-enoyloxypropoxy)propoxy]propyl prop-2-enoate offer alternative functionalities for more complex polymerization systems. OYSI maintains reliable supply chains for hexyl prop-2-enoate to support European industrial requirements with appropriate technical documentation and safety data sheets.
