(2-Aminoethyl)diphenylphosphine oxide is used as an extractant for the separation and purification of metals, particularly uranium. It forms stable complexes with metal ions, making it useful in the recovery of metals from ores and waste streams.
Used in Analytical Chemistry:
(2-Aminoethyl)diphenylphosphine oxide is used as a chelating agent for the determination of metal ions in complex samples. Its ability to form stable complexes with metal ions makes it a valuable tool in analytical chemistry for accurate metal ion analysis.

Check Digit Verification of cas no

The CAS Registry Mumber 33921-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,2 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33921-17:
(7*3)+(6*3)+(5*9)+(4*2)+(3*1)+(2*1)+(1*7)=104
104 % 10 = 4
So 33921-17-4 is a valid CAS Registry Number.

, p. 424 - 426 (2007/10/03)

Novel sugar-based azacrown ethers with phosphinoxido-alkyl side chain (2a-e) have been synthesized. They show significant asymmetric induction as phase transfer catalysts in the Michael addition of 2-nitropropane to chalcone (95% ee) and to 3-fur-2-yl-1-phenyl-propenone (80% ee).
