14452-57-4 Usage
Description
Magnesium dioxide, also known as magnesia, is a white powder with chemical properties that include being white or slightly yellow, amorphous, and light. It is noncombustible but can accelerate the burning of combustible material, especially if the material is finely divided, making the mixture potentially explosive. Magnesium dioxide is used in various applications due to its unique properties.
Uses
Used in Medicine:
Magnesium dioxide is used as an antacid for treating hyperacidity in the gastric intestinal tract. It is also utilized in the treatment of metabolic diseases such as diabetes and ketonuria. The compound is often mixed with other magnesium compounds like magnesium peroxide, magnesium oxide, magnesium hydroxide, and magnesium carbonate to enhance its effectiveness.
Used in Dental Care:
In the dental industry, magnesium dioxide is used as an ingredient in the preparation of toothpaste. Its properties contribute to maintaining oral health and hygiene.
Used in Pharmaceutical Preparations:
Magnesium dioxide is used in the formulation of antiseptic ointments, providing a soothing and protective effect on the skin.
Used as a Bleaching Agent:
In the textile and paper industries, magnesium dioxide serves as a bleaching agent due to its oxidizing properties, which help in whitening fabrics and paper products.
Used in Agricultural Applications:
Magnesium dioxide is also utilized in agriculture, where it can improve soil quality and provide essential nutrients to plants.
Air & Water Reactions
Insoluble in water and slowly decomposed by water, liberating oxygen.
Reactivity Profile
Mixtures of combustible material and the peroxide can be ignited with friction or moisture [AAR 1991]. Water gradually decomposes Magnesium dioxide liberating oxygen, with dilute acids Magnesium dioxide forms hydrogen peroxide, when strongly heated Magnesium dioxide losses all peroxide oxygen [Merck 11th ed. 1989].
Hazard
Powerful oxidizer and dangerous fire risk,
reacts with acidic materials and moisture.
Health Hazard
Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
Fire Hazard
These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
Safety Profile
A powerful oxidizer.
Probably a severe irritant to the eyes, skin,
and mucous membranes. Flammable by
chemical reaction with acidic materials and
moisture; an oxidizing agent. Dangerous;
reacts vigorously with reducing agents; will
decompose violently in or near a fire. See

PEROXIDES, INORGANIC.
Check Digit Verification of cas no
The CAS Registry Mumber 14452-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,4,5 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14452-57:
(7*1)+(6*4)+(5*4)+(4*5)+(3*2)+(2*5)+(1*7)=94
94 % 10 = 4
So 14452-57-4 is a valid CAS Registry Number.
