Chemical Description

Hypophosphorous acid is a phosphorus oxyacid with the chemical formula H3PO2.

Check Digit Verification of cas no

The CAS Registry Mumber 6303-21-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,0 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6303-21:
(6*6)+(5*3)+(4*0)+(3*3)+(2*2)+(1*1)=65
65 % 10 = 5
So 6303-21-5 is a valid CAS Registry Number.

Oxidation of white phosphorus by peroxides in water

Abdreimova,Akbaeva,Polimbetova

, p. 1873 - 1876 (2017/09/27)

A mixture of hypophosphorous, phosphorous, and phosphoric acids is formed during the anaerobic oxidation of white phosphorus by peroxides [ROOН; R = Н, 3-ClC6H4CO, (СН3)3С] in water. The rate of reactions grows considerably upon adding nonpolar organic solvents. The activity series of peroxides and solvents are determined experimentally. NMR spectroscopy shows that the main product of the reaction is phosphorous acid, regardless of the nature of the peroxide and solvent. A radical mechanism of oxidation of white phosphorus by peroxides in water is proposed. It is initiated by the homolysis of peroxide with the formation of НO? radicals that are responsible for the homolytic opening of phosphoric tetrahedrons. Further oxidation and stages of the hydrolysis of intermediate phosphorus-containing compounds yield products of the reaction.

Electrochemical generation of P4 2- dianion from white phosphorus

Yakhvarov,Gorbachuk,Khayarov, Kh. R.,Morozov,Rizvanov, I. Kh.,Sinyashin

, p. 2423 - 2427 (2015/08/03)

Electrochemical reduction of elemental (white) phosphorus in an undivided cell equipped with a sacrificial metal anode (Al, Co, Nb, Sn) results in the formation of the reduced form of white phosphorus, P4 2- dianion, which was detected in solution by 31P NMR spectroscopy.
