Phosphine oxide, (chloromethyl)methylphenyl-, also known as (chloromethyl)methylphenylphosphine oxide or (chloromethyl)methylphenylphosphine oxide, is an organophosphorus compound with the chemical formula C8H10ClO2P. It is a colorless to pale yellow liquid with a molecular weight of 210.61 g/mol. Phosphine oxide, (chloromethyl)methylphenyl- is characterized by the presence of a phosphorus atom bonded to an oxygen atom, a phenyl group, and a chloromethyl group. It is used as an intermediate in the synthesis of various organophosphorus compounds, such as pesticides, flame retardants, and pharmaceuticals. Due to its reactivity and potential toxicity, it is important to handle Phosphine oxide, (chloromethyl)methylphenyl- with care and follow proper safety guidelines.

1806-50-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1806-50-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,0 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1806-50:
(6*1)+(5*8)+(4*0)+(3*6)+(2*5)+(1*0)=74
74 % 10 = 4
So 1806-50-4 is a valid CAS Registry Number.

Phosphinylmethylphosphinates as chelating ligands

King,Block,Popoff

, p. 198 - 202 (2007/10/09)

(Dimethylphosphinyl)-, (methylphenylphosphinyl)-, and (diphenylphosphinyl)methylphenylphosphinic acids have been prepared by hydrolysis of the Michaelis-Arbuzov reaction products of the appropriate chloromethylphosphine oxides and diethyl phenylphosphonite. They react with Zn(C2H3O2)2·2H2O and Cr(C5H7O2)3 under suitable conditions to yield the corresponding bis and tris chelates, except for the diphenyl-chromium(III) derivative, which was prepared in low yield via the chromium(II) derivative. The zinc derivatives are dimers, the chromium derivatives monomers. The metal chelates are more thermally stable than the corresponding acetylacetonates. Their infrared and 1H n.m.r. spectra are discussed.
