1765-48-6 Usage
General Description
11H-PERFLUOROUNDECANOIC ACID is a synthetic chemical compound with the molecular formula C11HF19O2. It is a perfluorinated carboxylic acid, which means it contains a fully fluorinated carbon chain and a carboxylic acid functional group. 11H-PERFLUOROUNDECANOIC ACID is used in various industrial applications, including as a surfactant in the production of fluorinated polymers and as a surface treatment agent for water-repellent coatings. It is also used in the production of firefighting foams and in the manufacturing of various consumer products, such as non-stick coatings and stain-resistant fabrics. 11H-PERFLUOROUNDECANOIC ACID is known to be environmentally persistent and has been found to accumulate in the environment and in living organisms, leading to concerns about its potential toxicity and environmental impact.
Check Digit Verification of cas no
The CAS Registry Mumber 1765-48-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,6 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1765-48:
(6*1)+(5*7)+(4*6)+(3*5)+(2*4)+(1*8)=96
96 % 10 = 6
So 1765-48-6 is a valid CAS Registry Number.

Conformational energies of perfluoroalkanes. 5. Dipole moments of H(CF2)nH and H(CF2)nI
Matsuo, Keizo,Stockmayer, Walter H.
, p. 3307 - 3311 (2007/10/02)
Dielectric and refractive index increments at 25°C are reported for some α,ω-dihydroperfluoroalkanes and α-hydro-ω-iodoperfluoroalkanes in benzene and CCl4. Similar measurements on perfluorocyclohexane and perfluoro-n-hexane are used to deduce effective atomic polarizations for fluorocarbons in solution. The dipole moments obtained lead to a somewhat smaller characteristic ratio for the perfluoroalkane chain than had earlier been estimated by Bates and Stockmayer.
