Description

p-10-Undecen-1-Yl-Phosphonic Acid is a specialized organophosphorus compound featuring a terminal alkene group, making it a versatile building block for surface modification and polymer chemistry. Its bifunctional structure is critical for creating durable, covalently bonded monolayers on metal oxide surfaces, particularly in high-performance applications. This chemical is essential for R&D and production teams in the advanced materials, nanotechnology, and specialty coatings sectors seeking to engineer surfaces with specific functional properties.

Application

• Surface Modification Agent: Key for forming self-assembled monolayers (SAMs) on aluminum, steel, and other metal oxides to alter surface energy, enhance corrosion resistance, or provide a reactive platform for further functionalization.
• Adhesion Promoter: Used in primer formulations to improve the bonding of paints, adhesives, and composite materials to metallic substrates.
• Lubricant & Anti-Wear Additive: Serves as a precursor for boundary lubrication films in advanced lubricant formulations for demanding mechanical systems.
• Dental & Biomedical Coatings: Employed to functionalize titanium and other implantable alloy surfaces to promote osseointegration or reduce bacterial adhesion.
• Polymer & Resin Modification: The phosphonic acid and alkene groups allow for copolymerization or grafting, introducing phosphorus functionality into polymers for flame retardancy or metal chelation.
• Nanoparticle Functionalization: Used to stabilize and tailor the surface properties of metal oxide nanoparticles (e.g., ZnO, TiO2) for use in catalysis, sensors, or nanocomposites.
• Corrosion Inhibitor Precursor: Acts as a chemisorbing agent to create protective layers on metals, forming the basis for "green" or non-chromate corrosion inhibition systems.
• Research & Development: A valuable intermediate in organic synthesis and materials science research for developing new functional molecules and hybrid materials.

Quality Control

Our p-10-Undecen-1-Yl-Phosphonic Acid is produced and tested under a strict quality management system. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and titration methods, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties 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). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
