Isooctyl Methacrylate, identified by CAS number 28675-80-1, is a key chemical intermediate widely utilized in the synthesis of polymers, resins, and various specialty chemicals. As a methacrylate ester, its molecular structure confers properties essential for applications ranging from industrial coatings and adhesives to advanced biomedical materials. For professionals seeking to purchase this compound, understanding its characteristics, how it's made, and how to source it effectively is crucial.

Chemical Properties and Characteristics:

The core structure of Isooctyl Methacrylate consists of a methacrylate group esterified with an isooctyl alcohol moiety. This grants it:

  • Polymerizability: The double bond in the methacrylate group is highly reactive and readily undergoes free-radical polymerization. This property is fundamental to its use in creating polymers and copolymers.
  • Hydrophobicity and Flexibility: The branched eight-carbon isooctyl chain provides a significant hydrophobic character and can impart flexibility to the resulting polymers, often lowering their glass transition temperature (Tg). This is advantageous for applications requiring impact resistance or soft, pliable materials.
  • Solubility: It exhibits good solubility in common organic solvents, facilitating its use in various polymerization and formulation processes.
  • Reactivity: While primarily known for polymerization, the ester group can also undergo hydrolysis under harsh conditions. It is typically stabilized with inhibitors to prevent premature polymerization during storage and handling.

Synthesis Methods:

The most common method for synthesizing Isooctyl Methacrylate is through the direct esterification of methacrylic acid with isooctyl alcohol. This reaction is typically catalyzed by a strong acid, such as sulfuric acid or p-toluenesulfonic acid. To prevent unintended polymerization of the monomer during synthesis and purification, polymerization inhibitors (e.g., hydroquinone or MEHQ) are added. The process often involves controlling temperature and applying vacuum to drive the reaction to completion and remove water as a byproduct. Purification steps, such as vacuum distillation, are then employed to isolate the high-purity Isooctyl Methacrylate required for many applications.

Sourcing Isooctyl Methacrylate: A Buyer's Perspective

When looking to buy Isooctyl Methacrylate, several factors are critical for ensuring a successful procurement:

  • Purity and Specifications: Always verify the product's purity (e.g., >95% or >98%) and check for the presence of inhibitors, residual acids, or moisture. A detailed Certificate of Analysis (CoA) from the manufacturer is essential.
  • Manufacturer vs. Distributor: While distributors can offer convenience, sourcing directly from a reputable 'isooctyl methacrylate manufacturer' can often lead to better pricing, especially for bulk quantities, and a more direct line to technical support.
  • Price and Value: When comparing 'cas 28675-80-1 price,' consider the total value proposition, which includes product quality, supply reliability, technical support, and logistical efficiency. A slightly higher price from a trusted supplier might be more economical in the long run due to reduced risks of production downtime or product failure.
  • Supply Chain Reliability: For industrial applications, a consistent and stable supply chain is paramount. Inquire about the manufacturer's production capacity, lead times, and inventory management. A 'chemical manufacturer' with a global reach, such as those based in China, often offers competitive advantages.
  • Technical Support: Having access to technical data and support from the supplier can be invaluable for optimizing its use in your specific formulations and processes.

In conclusion, Isooctyl Methacrylate is a vital component in numerous chemical industries. By understanding its properties, synthesis, and by carefully selecting a trusted manufacturer and supplier, businesses can secure a high-quality, cost-effective source for this essential chemical intermediate, driving innovation and ensuring product excellence.
