For professionals in chemical procurement and R&D, a thorough understanding of the compounds they source is crucial. 2-(Perfluorohexyl)ethyl Methacrylate (CAS 2144-53-8) is a highly specialized monomer that offers unique properties derived from its fluorinated structure. This article delves into its chemistry, synthesis, and the strategic considerations for sourcing this vital chemical intermediate.

Chemical Identity and Properties

The chemical structure of 2-(Perfluorohexyl)ethyl Methacrylate (PFEMA) features a methacrylate group (CH2=C(CH3)COO-) esterified with a 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctan-1-ol. This results in the molecular formula C12H9F13O2 and a molecular weight of 432.18 g/mol. Key physical properties include:

  • Appearance: Colorless transparent liquid.
  • Purity: Typically specified as ≥98% or ≥99% for high-grade applications.
  • Boiling Point: Approximately 92 °C at 8 mmHg.
  • Density: Around 1.496 g/mL at 25 °C.
  • Solubility: Soluble in many organic solvents, sparingly soluble in methanol, and has low solubility in water.

The presence of the perfluorohexyl chain, characterized by six CF2 groups and a terminal CF3 group, is responsible for the compound's low surface energy, high thermal stability, and excellent chemical resistance. These characteristics make it a preferred choice for manufacturers looking to buy materials that offer superior performance in challenging environments.

Synthesis and Manufacturing Considerations

The synthesis of PFEMA commonly involves the esterification of methacrylic acid or its derivatives with 1H,1H,2H,2H-perfluorooctanol. This process requires careful control of reaction conditions to ensure high yields and purity, often involving catalysts and purification steps like distillation. As a Chinese chemical supplier, we adhere to strict manufacturing protocols to deliver a consistent and high-quality product.

Industrial Applications Driven by Performance

PFEMA's utility spans several high-value applications:

  • Surface Modifiers: Its ability to lower surface energy is invaluable in creating hydrophobic and oleophobic surfaces for textiles, coatings, and specialty papers. Buyers often target this monomer for its role in imparting stain and water repellency.
  • Polymer Synthesis: As a monomer, it is polymerized or copolymerized to create fluorinated polymers. These polymers find use in advanced composites, sealants, and materials requiring non-stick properties or resistance to extreme conditions.
  • Intermediate for Specialty Chemicals: It serves as a precursor for other complex fluorinated compounds, including surfactants and active pharmaceutical ingredients (APIs), where the fluorinated tail is critical for biological activity or performance.
