7526-29-6 Usage
General Description
Phosphonic acid, ethyl-, diphenyl ester, also known as ethyl diphenyl phosphonate, is a chemical compound commonly used as a flame retardant, plasticizer, and anti-wear additive in various industrial and commercial applications. It is an organophosphorus compound with the chemical formula C14H17O3P and a molecular weight of 270.26 g/mol. The compound is a clear, colorless to light yellow liquid with a faint odor, and it is insoluble in water but soluble in organic solvents like ethanol and acetone. It is also known for its low volatility and high thermal stability, making it suitable for use in high-temperature applications. However, it is important to handle this chemical with care as it can be harmful if ingested, inhaled, or comes in contact with the skin or eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 7526-29-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,2 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7526-29:
(6*7)+(5*5)+(4*2)+(3*6)+(2*2)+(1*9)=106
106 % 10 = 6
So 7526-29-6 is a valid CAS Registry Number.

We describe a high radiochemical yield late-stage direct 18F-labeling of bare biomolecules containing common active groups. Spontaneity and site-selectivity are attributed to the remarkably higher rates of nucleophilic substitution reactions on phosphonates than on other electrophiles by F- at various hydrogen bond forms. Rapid access to many medicinally significant 18F-labeled biomolecules is achieved at 21-68% radiochemical yields and 35.9-55.1 GBq μmol-1 molar activities both manually or automatically.
