Description

1,2-Bis(11-Hydroxyundecyloxy)Benzene is a high-purity, long-chain diol derivative of catechol, characterized by its terminal primary hydroxyl groups and aromatic ether linkages. This unique bifunctional structure makes it a valuable intermediate and monomer for synthesizing specialized polymers and functional materials. It is primarily sought by R&D and production teams in the advanced materials, polymer chemistry, and specialty chemical sectors for creating novel polyesters, polyurethanes, and liquid crystal polymers.

Application

• Polymer Synthesis: Key monomer for producing high-performance polyesters and polycarbonates with tailored flexibility and thermal properties.
• Specialty Polyurethanes: Serves as a chain extender or crosslinker to modify elastomer and foam characteristics, such as resilience and hydrolytic stability.
• Liquid Crystal Polymers (LCPs): Used as a mesogenic diol component in the synthesis of thermotropic LCPs for electronics and high-strength fibers.
• Surface Modifiers & Coatings: Intermediate for creating surfactants, lubricants, or coating additives that require specific hydrophobic/hydrophilic balance.
• Pharmaceutical & Agrochemistry Intermediates: Building block for synthesizing complex molecules in advanced research and development.
• Crosslinking Agent: Utilized in epoxy resin systems and other thermosetting polymers to enhance mechanical strength and chemical resistance.
