Description

(2-Amino-3-Hydroxy-Octadecoxy)Phosphonic Acid is a high-purity, organophosphorus compound characterized by its unique amphiphilic structure, combining a long alkyl chain with amino, hydroxy, and phosphonic acid functional groups. This molecular architecture makes it a valuable intermediate and functional additive, particularly effective as a chelating agent and surface modifier. It is essential for industries requiring specialized phosphonate chemistry, such as advanced material synthesis, pharmaceutical research, and the formulation of high-performance detergents and corrosion inhibitors. Our supply ensures consistent quality and reliable availability for your critical R&D and production needs.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel bioactive molecules and prodrugs, particularly those targeting bone metabolism or requiring metal chelation.
• Specialty Surfactant & Detergent Formulations: Acts as a functional surfactant and chelating agent in industrial and institutional cleaning products, enhancing performance in hard water.
• Corrosion and Scale Inhibition: Used in water treatment systems, cooling towers, and oilfield applications to prevent scale formation and protect metal surfaces due to its strong metal-sequestering properties.
• Material Science & Nanotechnology: Employed as a surface-modifying agent or ligand for functionalizing nanoparticles, quantum dots, and other advanced materials to improve dispersion and stability.
• Agricultural Chemistry: Investigated for use in the development of specialized herbicides, plant growth regulators, or nutrient delivery systems that utilize phosphonate chemistry.
• Laboratory Research & Chemical Synthesis: A versatile reagent for organic and medicinal chemistry research, enabling the introduction of phosphonic acid groups into complex molecular frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which may affect product stability and performance.
