11062-77-4 Usage
Description
Superoxide is a group of inorganic compounds characterized by the presence of the O2ion in their structure. The O2ion has an odd number of electrons (17), making all superoxide compounds paramagnetic. These compounds exhibit a yellowish color at room temperature and undergo reversible phase transitions accompanied by a color change to white at low temperatures. The stable superoxides include 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), and tetramethylammonium superoxide ((CH3)4NO2). In these compounds, each oxygen atom has an oxidation number of -1/2 instead of -2, as in normal oxides. Superoxides are also products of the univalent reduction of O2 or the univalent oxidation of H2O2 and are generated both enzymatically and nonenzymatically in biological systems.
Uses
1. Used in Chemical Reactions:
Superoxide is used as a strong reducing agent in various chemical reactions due to its relatively negative dioxygen/superoxide couple (Eo0 = -20.31 V). It readily reduces oxidized cytochrome C and other measurable oxidants such as tetrazolium salts.
2. Used in Detection Methods:
Superoxide is used in the detection of various compounds and substances through methods like optical spectroscopy, electron spin resonance, mass spectrometry, and detection based on its ability to reduce readily measurable oxidants.
3. Used in Oxygen Generation:
Superoxides, particularly those of sodium, potassium, rubidium, and caesium, are used in the generation of oxygen gas when they react vigorously with water, producing oxygen gas and OHions.
4. Used in Oxidation Processes:
Due to their powerful oxidizing properties, superoxides are used in various oxidation processes, particularly in the chemical and industrial applications where strong oxidizing agents are required.
5. Used in Research and Development:
Superoxides are utilized in research and development for understanding their properties, reactivity, and potential applications in various fields, including materials science, pharmaceuticals, and environmental science.
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.
