Description

3,7-Dimethylocta-2,6-Dienyl Methacrylate is a specialized methacrylate ester monomer derived from a terpene alcohol backbone. This compound matters for its unique combination of a reactive methacrylate group with the hydrophobic and potentially bio-based character of a citronellyl-like structure, enabling the synthesis of polymers with tailored properties. It is primarily needed by R&D chemists and formulators in the specialty polymer, adhesive, and advanced material sectors seeking to modify polymer characteristics such as hydrophobicity, flexibility, and compatibility.

Application

• Specialty Polymer Synthesis: As a co-monomer for creating acrylic polymers with enhanced hydrophobicity, low surface energy, and specific solubility profiles.
• Pressure-Sensitive Adhesives (PSAs): To modify tack, peel strength, and aging properties in adhesive formulations for tapes and labels.
• Coatings and Inks: Imparting flexibility, adhesion to low-energy surfaces, and resistance to chemicals in industrial and graphic arts coatings.
• UV-Curable Resins: Serving as a reactive diluent or functional monomer in systems cured by ultraviolet light for fast, solvent-free applications.
• Biomaterial Modification: Potential use in creating functionalized polymers for controlled release or surface modification in biomedical research.
• Fragrance and Flavor Chemistry: As a synthetic intermediate for producing esters with specific olfactory characteristics.

Quality Control

Our 3,7-Dimethylocta-2,6-Dienyl Methacrylate is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure consistent purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, isomer content, and inhibitor level is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its reactivity, it should be stored separately from strong acids and oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
