11062-77-4 Usage

Description

Different sources of media describe the Description of 11062-77-4 differently. You can refer to the following data:
1. A compound characterized by the presence in its structure of the O2? ion. The O2? ion has an odd number of electrons (17) and as a result all superoxide compounds are paramagnetic. At room temperature they have a yellowish color. At low temperature many of them undergo reversible phase transitions accompanied by a color change to white. The stable superoxides are sodium superoxide NaO2 potassium superoxide KO2 rubidium superoxide RbO2 cesium superoxide CsO2 calcium superoxide Ca(O2)2 strontium superoxide Sr(O2)2 barium superoxide Ba(O2)2 tetramethylammonium superoxide (CH3)4NO2 In these compounds each oxygen atom has an oxidation number of ?1/2 instead of ?2, as a normal oxide.
2. A product of the univalent reduction of O2 or the univalent oxidation of H2O2. The superoxide radical (O22 ) or its corresponding acid (perhydroxyl radical, HO2; pKa 5 4.8) is generated both enzymatically and nonenzymatically in biological systems. Superoxide can also be produced by cathodic reduction of O2 in an aprotic solvent, as well as by ultrasonication, pulse radiolysis, or photolysis of water. By virtue of a relatively negative dioxygen/superoxide couple (Eo0 5 20.31 V) superoxide is a stronger reductant than it is an oxidant (i.e., it readily reduces oxidized cytochrome C). Detection methods include optical spectroscopy, electron spin resonance, mass spectrometry, and detection of its presence based on its ability to reduce readily measurable oxidants such as cytochrome c or tetrazolium salts. Due to its reductive ability as well as the spontaneous disproportionation that proceeds with a rate constant of about 105 M21 sec21 (O22 1 O22 1 2H1-H2O2 1 O2), the steady-state concentrations of the oxyradicals are usually low at physiological conditions.

Definition

Different sources of media describe the Definition of 11062-77-4 differently. You can refer to the following data:
1. An inorganic compound containing the O2– ion.
2. superoxides: group of inorganiccompounds that contain the O2– ion.They are formed in significant quantitiesonly for sodium, potassium, rubidium,and caesium. They are verypowerful oxidizing agents and reactvigorously with water to give oxygengas and OH– ions. The superoxide ionhas an unpaired electron and is paramagneticand coloured (orange).

Check Digit Verification of cas no

The CAS Registry Mumber 11062-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,0,6 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 11062-77:
(7*1)+(6*1)+(5*0)+(4*6)+(3*2)+(2*7)+(1*7)=64
64 % 10 = 4
So 11062-77-4 is a valid CAS Registry Number.

Enhanced nitric oxide generation mitigates cadmium toxicity via Superoxide (cas 11062-77-4) scavenging leading to the formation of peroxynitrite in barley root tip07/16/2019

The aim of this study was to observe the possible function of increased superoxide and NO production in the response of barley root tip to the harmful level of Cd. While superoxide generation was detected only in the transition zone, the formation of NO was observed in the apical elongation zone...detailed
