Description
N-octadecylphosphonic acid (OPA) is a crystalline solid that is a type of long chain phosphonic acid compound. It is known for its ability to form self-assembled monolayers, acting as a surfactant that strongly bonds with the surface atoms of various metal oxides. This property allows OPA to provide hydrophobic characteristics and cover a larger surface area compared to commonly used silanes.
Uses
Used in Detergents, Dispersants, Emulsifiers, and Chelating Agents:
N-octadecylphosphonic acid is used as a surfactant, emulsifier, dispersant, and chelating agent in the production of detergents, dispersants, emulsifiers, and chelating agents. Its ability to neutralize to phosphonates at neutral to high pH increases its solubility in water, making it an effective component in these applications.
Used in Thermal Paper for Receipts, Adding Machines, and Tickets:
In the thermal paper industry, N-octadecylphosphonic acid serves as a surfactant, emulsifier, dispersant, and chelating agent. Its role in this application is crucial for the proper functioning of receipts, adding machines, and tickets.
Used in Proteomics Research:
N-octadecylphosphonic acid is also utilized in proteomics research, where it aids in the study of proteins and their interactions within a biological system.
Used in Modified Mesoporous Magnetic Nanoparticles Preparation:
OPA is employed in the preparation of modified mesoporous magnetic nanoparticles through Lewis acid/base interaction, which is essential for various applications in the field of nanotechnology.
Check Digit Verification of cas no
The CAS Registry Mumber 4724-47-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4724-47:
(6*4)+(5*7)+(4*2)+(3*4)+(2*4)+(1*7)=94
94 % 10 = 4
So 4724-47-4 is a valid CAS Registry Number.

Here, we synthesized 2-ethylhexyl, 2-hexyldecyl, 2-[2-(2-methoxyethoxy)ethoxy]ethyl, oleyl, and n-octadecyl phosphonic acid and used them to functionalize CdSe and HfO2 nanocrystals. In contrast to branched carboxylic acids, postsynthetic surface functionalization of CdSe and HfO2 nanocrystals was readily achieved with branched phosphonic acids. Phosphonic acid capped HfO2 nanocrystals were subsequently evaluated as memristors using conductive atomic force microscopy. We found that 2-ethylhexyl phosphonic acid is a superior ligand, combining a high colloidal stability with a compact ligand shell that results in a record-low operating voltage that is promising for application in flexible electronics.
Synthesis and structural study of long-chain hydrocarbon alkylphosphonic acids

Long-chain dialkyl alkylphosphonates were synthesized by radical addition of dialkyl hydrogenphosphonates onto alkenes in presence of di(t-butyl) peroxide. This synthetic route leads to high yields between 94 and 97%. We performed chemical modifications of these phosphonates in order to obtain acidic derivatives. The structure of these compounds was characterized by NMR analyses and mass spectroscopy. We also studied their thermal behaviour and various crystalline phases were put in evidence by differential scanning calorimetry and optical microscopy. The thermal stability of these compounds was compared by thermogravimetric analyses.
