Description

Cyclohexane-1,2-Dicarboxylic Acid Di(2,7-Octadienyl) Ester is a specialized diester derivative of cyclohexane-1,2-dicarboxylic acid, valued for its unique molecular structure featuring unsaturated side chains. This compound matters as a versatile chemical intermediate and functional additive, offering properties such as plasticization and reactivity that are essential for advanced material synthesis. Industrial users in polymer modification, specialty adhesives, and advanced coating formulations require this ester for developing products with enhanced flexibility, adhesion, and performance characteristics.

Application

• Polymer Plasticizer: Acts as a specialty plasticizer and co-monomer in the production of flexible PVC, synthetic rubbers, and other polymer systems to improve low-temperature performance and elasticity.
• Adhesive & Sealant Formulations: Serves as a reactive diluent and tackifier component in high-performance industrial adhesives, sealants, and pressure-sensitive adhesive (PSA) formulations.
• Coating Resins: Used as a building block in the synthesis of alkyd resins, polyesters, and other coating binders to enhance film flexibility, durability, and adhesion to substrates.
• Lubricant & Grease Additive: Functions as a synthetic base oil or an additive component in specialty lubricants and greases, contributing to thermal stability and lubricity.
• Chemical Intermediate: Provides a platform for further chemical synthesis, including Diels-Alder reactions and hydrogenation, due to its reactive dienyl groups, leading to novel fine chemicals.
• Crosslinking Agent: Utilized in radiation-curable coatings and inks where its unsaturated bonds participate in crosslinking reactions to form durable polymer networks.

Quality Control

Our Cyclohexane-1,2-Dicarboxylic Acid Di(2,7-Octadienyl) Ester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and compliance with agreed specifications. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, open flames, and strong oxidizing agents. For long-term storage, consider maintaining under an inert gas atmosphere such as nitrogen or argon to preserve product integrity.
