Product Description

Product Description

 

 N-Octylphosphonic Acid (CAS 4724-48-5)
High-Performance Organophosphorus Compound for Surface Modification and Catalysis

N-Octylphosphonic Acid, systematically named octylphosphonic acid. This monofunctional phosphonic acid combines a hydrophobic octyl chain with a reactive phosphonic acid group, enabling unique interfacial activity. It exhibits excellent solubility in polar organic solvents  and limited solubility in water (<1 g/L at 20°C). The compound demonstrates thermal stability up to 200°C under inert atmospheres and complies with REACH registration requirements.

Key Industrial Applications
·Metal Surface Treatment:
Corrosion inhibitor for steel and aluminum alloys
Self-assembled monolayer (SAM) precursor for nanotechnology coatings
 
·Lubricant Additives:
Extreme pressure (EP) additive in cutting fluids and gear oils
Anti-wear modifier for boundary lubrication systems
·Extraction & Separation:
Solvent extractant for rare earth element recovery
Ion-selective agent in membrane technologies
·Polymer Industry:
Coupling agent in polymer-clay nanocomposites
Co-monomer for flame-retardant polymer synthesis
·Electronics Manufacturing:
Surface modifier for oxide semiconductors in photovoltaic devices
Etching solution component for microelectronic patterning
