Octadecylphosphonic Acid (ODPA), with its molecular formula C18H39O3P, is a fascinating organic compound that holds significant importance in both industrial applications and scientific research. NINGBO INNO PHARMCHEM CO.,LTD. provides this crucial chemical, enabling various technological advancements.

At its core, ODPA is a long-chain phosphonic acid. Its structure features an eighteen-carbon alkyl chain (octadecyl) attached to a phosphonic acid functional group (-PO(OH)2). This bifunctional nature is key to its utility. The long, hydrophobic octadecyl chain imparts solubility in organic solvents and contributes to its surface-active properties. Conversely, the phosphonic acid group is polar and hydrophilic, capable of forming strong bonds with metal surfaces and interacting with polar substances.

Chemically, ODPA is typically a white crystalline solid with a melting point around 95-100°C. It is noted for its stability, although it is incompatible with strong oxidizing agents. Its insolubility in water is a characteristic derived from the long hydrocarbon chain. However, when neutralized to its phosphonate form at higher pH, its water solubility increases.

The reactivity of the phosphonic acid group is central to many of ODPA's applications. It can undergo esterification, form salts, and crucially, chemisorb onto metal oxide surfaces. This chemisorption leads to the formation of stable self-assembled monolayers (SAMs). The ordered packing of these ODPA molecules on a surface creates a barrier that can modify surface energy, impart water repellency, and protect against corrosion. The ability to buy Octadecylphosphonic Acid and utilize its surface modification capabilities is a major draw for industries.

In scientific research, these properties are leveraged for advanced studies. ODPA is utilized in proteomics research and for synthesizing functionalized nanoparticles. Its use in preparing modified mesoporous magnetic nanoparticles, for instance, showcases its role in advanced materials science and nanotechnology. The price of Octadecylphosphonic Acid can vary based on purity and supplier, but its unique chemical properties often justify the investment for specialized applications.

Understanding the chemical significance of Octadecylphosphonic Acid is crucial for anyone looking to utilize its full potential. From its foundational role in thermal paper technology to its emerging applications in surface engineering and nanotechnology, ODPA remains a chemical of considerable importance.
