1093-62-5 Usage
General Description
(2-phenoxyphenyl)phenylphosphinic acid is a chemical compound with the formula C18H15O3P. It is classified as an organophosphorus compound and is often used as a precursor in the synthesis of various phosphine oxides, which have applications in catalysis and as ligands in coordination chemistry. (2-phenoxyphenyl)phenylphosphinic acid is also known to possess insecticidal properties and has been studied for its potential use as a pesticide. Additionally, it has been investigated for its potential use in the production of flame retardants and polymer additives due to its unique chemical structure and properties. However, it is important to note that (2-phenoxyphenyl)phenylphosphinic acid may pose certain health and environmental hazards and should be handled with care in accordance with proper safety protocols.
Check Digit Verification of cas no
The CAS Registry Mumber 1093-62-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,9 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1093-62:
(6*1)+(5*0)+(4*9)+(3*3)+(2*6)+(1*2)=65
65 % 10 = 5
So 1093-62-5 is a valid CAS Registry Number.

Experimental and quantum chemical studies of 2-phosphinylphenol derivatives
Levy, Jack B.,Sutton, Steven B.,Olsen, Ronald E.

Carbon-oxygen bonds ortho to a phosphoryl group in triarylphosphine oxides undergo cleavage when the oxides are either fused with potassium hydroxide or treated with potassium tert-butoxide in refluxing toluene, presumably through a nucleophilic addition-elimination mechanism. Thus, bis(2-hydroxyphenyl)phenylphosphine oxide is produced along with the expected 2-phenoxyphenyl(phenyl)phosphinic acid from 10-phenyl-10H-phenoxaphosphine 10-oxide. The latter starting material is also produced, together with bis(2-hydroxyphenyl)phenylphosphine oxide, when bis(2-methoxyphenyl)phenylphosphine oxide is fused with potassium hydroxide. Fusion of bis(2-methoxyphenyl)phenylphosphine oxide with sodium hydroxide, however, yields 2-hydroxyphenyl(phenyl)phosphinic acid. Ab initio quantum chemical studies confirm that the downfield 31P chemical shift that is observed in 2-phosphinylphenols is due to hydrogen bonding to the phosphoryl group.
