Description

Diethyl 11-Hydroxyundecylphosphonate, 95% is a high-purity organophosphorus compound featuring a terminal hydroxyl group on a long alkyl chain, making it a versatile bifunctional building block. This structure is critical for synthesizing specialized surfactants, lubricant additives, and polymer modifiers where precise hydrophile-lipophile balance and phosphorus functionality are required. It is essential for R&D and production chemists in the specialty chemicals, advanced materials, and pharmaceutical intermediates sectors seeking to incorporate phosphonate and alcohol moieties into target molecules.

Application

• Phosphorus-Containing Surfactant Synthesis: Serves as a key intermediate for producing anionic or nonionic surfactants with enhanced metal-chelating and anti-corrosion properties.
• Lubricant and Fuel Additive Precursor: Used to manufacture extreme pressure (EP) additives and anti-wear agents for industrial lubricants and advanced fuel formulations.
• Polymer Modification Agent: The hydroxyl and phosphonate groups allow for grafting onto polymer backbones to impart flame retardancy, improved adhesion, or hydrophilicity.
• Pharmaceutical & AgroChemical Intermediates: Acts as a synthon for creating bioactive molecules, including prodrugs or compounds with specific phosphonate-based biological activity.
• Metal Extraction and Chelation: The phosphonate group is effective in formulating ligands for metal ion sequestration and extraction processes.
• Surface Treatment and Corrosion Inhibition: Used in formulations for coatings and treatments that protect metal surfaces.
• Research & Development: A valuable tool in organic synthesis for constructing complex molecules with tailored phosphonate ester linkages.
