545-82-4 Usage
Description
ODEPA, or octadecylphosphonic acid, is an organophosphorus compound characterized by a long-chain alkyl phosphonic acid structure with a C18H37 tail and a phosphonic acid head group. This unique composition renders ODEPA highly effective in modifying the surface properties of metal oxide nanoparticles, thereby controlling their surface energy and enhancing dispersion stability in various solvents.
Uses
Used in Nanotechnology:
ODEPA is used as a surface modifier for metal oxide nanoparticles to improve their dispersion stability in different solvents. This modification is crucial for enhancing the performance of nanoparticles in applications such as catalysis, coatings, and electronic devices.
Used in Composite Materials:
In the field of composite materials, ODEPA serves to strengthen the binding of metal oxide nanoparticles to metal oxide surfaces. This results in better compatibility with organic matrices and an overall improvement in the performance of the composite materials.
Used in Corrosion Inhibition:
ODEPA is utilized as a corrosion inhibitor for metal surfaces. It forms a protective phosphate layer that shields the metal from corrosion, thus prolonging the service life of metal components and structures.
Check Digit Verification of cas no
The CAS Registry Mumber 545-82-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 545-82:
(5*5)+(4*4)+(3*5)+(2*8)+(1*2)=74
74 % 10 = 4
So 545-82-4 is a valid CAS Registry Number.
