Description

Diethyl 12-Mercaptododecylphosphonate, 95% is a high-purity organophosphorus compound featuring a long alkyl chain terminated with a thiol (mercapto) group. This unique bifunctional structure makes it a valuable intermediate for creating specialized ligands, surface modifiers, and functional additives. It is particularly sought after by researchers and manufacturers in the fields of materials science, nanotechnology, and specialty polymer synthesis.

Application

• Surface Modification Agent: Used to functionalize metal nanoparticles (e.g., gold, silver) and metal oxide surfaces to impart stability and specific chemical reactivity.
• Polymer Additive & Crosslinker: Acts as a chain-transfer agent or crosslinking monomer in radical polymerizations to introduce phosphonate and thiol functionalities into polymers.
• Ligand Synthesis: Serves as a key precursor for synthesizing complex chelating ligands used in catalysis and metal ion extraction.
• Lubricant & Anti-wear Additive: The phosphonate and thiol groups can provide excellent anti-wear and extreme pressure properties when formulated into advanced lubricants.
• Corrosion Inhibitor Precursor: Used to develop novel corrosion-resistant coatings for metals, leveraging its ability to bind strongly to metal surfaces.
• Bioconjugation Linker: Facilitates the attachment of biomolecules to inorganic surfaces or other polymers in diagnostic and biomedical applications.

Quality Control

Our Diethyl 12-Mercaptododecylphosphonate, 95% is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the specified 95% minimum purity. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency for your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C to minimize oxidation of the thiol group and ensure long-term stability. Keep away from strong oxidizing agents.
