7486-26-2 Usage
Description
Sodium bromite (NaBrO2) is a chemical compound that is typically used in various industrial applications due to its unique properties. It is a white crystalline solid that is soluble in water and has a strong oxidizing nature.
Uses
Used in Chemical Industry:
Sodium bromite is used as an oxidizing agent for the preparation method of high-purity sodium bromite aqueous solution. Its strong oxidizing properties make it suitable for this application, allowing for the efficient production of the desired solution.
In addition to the chemical industry, sodium bromite may also have applications in other industries, such as the pharmaceutical or water treatment industries, due to its oxidizing properties.
Preparation
Bromous acid can thus be produced by a classical
chemical or an electrochemical method in which hypobromite
is oxidized to the bromite anion:
HBrO+ HClO→HBrO2+ HCl or HBrO+ H2O+ e- →HBrO2+ H2
Also disproportioning of hypobromous acid will give
bromous acid and hydrobromic acid:
2HBrO+ heat→HBrO2+ HBr
In addition, a rearrangement reaction of bromic acid
and hydrobromic acid will produce bromous acid:
2HBrO3+ HBr→3HBrO2
Check Digit Verification of cas no
The CAS Registry Mumber 7486-26-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,8 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7486-26:
(6*7)+(5*4)+(4*8)+(3*6)+(2*2)+(1*6)=122
122 % 10 = 2
So 7486-26-2 is a valid CAS Registry Number.

Bromite ion catalysis of the disproportionation of chlorine dioxide with nucleophile assistance of electron-transfer reactions between ClO2 and BrO2 in basic solution
Wang, Lu,Nicoson, Jeffrey S.,Huff Hartz, Kara E.,Francisco, Joseph S.,Margerum, Dale W.
, p. 108 - 113 (2008/10/08)
The rate of ClO2 conversion to ClO2- and ClO3- is accelerated by BrO2-, repressed by ClO2-, and greatly assisted by many nucleophiles (Br- > PO43- > HPO42- > CO32- > Cl- ~ OH- > CH3COO- ~ SO42- C5H5N ? H2O). The kinetics (at p[H+] = 9.3-12.9) show that the first step of the mechanism is an electron transfer between ClO2 and BrO2- (k1 = 36 M-1 s-1) to give ClO2- and BrO2. This highly reversible reaction (k1/k-1 = 1 × 10-6) accounts for the observed inhibition by ClO2-. The second step is an electron transfer between ClO2 and BrO2 to regenerate BrO2- and form ClO3-. A novel aspect of the second step is the large kinetic contribution from nucleophiles (kNu) that assist the electron transfer between ClO2 and BrO2. The kNu (M-2 s-1) values at 25.0 °C vary from 2.89 × 108 for Br- to 2.0 × 104 for H2O.
