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, is low-melting solid (melting point: ~25-28°C) with mild acidity. 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.
