7787-49-7 Usage
Uses
Used in Beryllium Metallurgy:
Beryllium fluoride is used in the manufacture of beryllium (Be) and its alloys, which are employed in various industries due to their unique properties.
Used in Glass Manufacturing:
Beryllium fluoride is utilized in the production of glass, contributing to its specific characteristics and quality.
Used in Nuclear Reactors:
Beryllium fluoride forms a basic constituent of the preferred fluoride salt mixture used in liquid-fluoride nuclear reactors. It is mixed with LiF to create a base solvent for introducing fluorides of uranium and thorium, offering exceptional chemical stability and optimal neutronic properties.
Used in Biochemistry and Protein Crystallography:
In biochemistry, particularly protein crystallography, beryllium fluoride is used because it binds in some of the same ways as phosphate does in human tissues. The combination of ADP and beryllium fluoride tends to bind to ATP sites and inhibit protein action, allowing for the crystallization of proteins in the bound state.
Used in Chemical Reduction Process:
Beryllium fluoride is also used alongside magnesium metal in the chemical reduction process to produce beryllium metal, taking advantage of its +2 oxidation state when combined with a negative anion element with an oxidation state of -1.
Preparation
Beryllium fluoride is made by thermal decomposition of ammonium beryllium fluoride at 900 to 950°C.
Air & Water Reactions
Water soluble.
Reactivity Profile
Beryllium fluoride is incompatible with the following: Acids, caustics, chlorinated hydrocarbons, oxidizers, magnesium, molten lithium .
Hazard
A known carcinogen. Toxic by inhalation and ingestion.
Health Hazard
Any dramatic weight loss should be considered as possible first indication of beryllium disease. Inhalation causes irritation of nose, throat, and lungs, severe pneumonitis, and/or pulmonary edema. Ingestion causes fatigue, weakness, loss of appetite. Contact with eyes causes severe irritation and burns. Contact with skin causes dermatitis and non-healing ulcers.
Fire Hazard
Special Hazards of Combustion Products: Toxic and irritating vapor of unburned material may form in fire.
Safety Profile
Confirmed carcinogen withexperimental carcinogenic and tumorigenic data byinhalation. Poison by ingestion, subcutaneous,intravenous, and intraperitoneal routes. Incompatible with Mg. When heated to decomposition, itemits very toxic fumes of BeO and F
Check Digit Verification of cas no
The CAS Registry Mumber 7787-49-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7787-49:
(6*7)+(5*7)+(4*8)+(3*7)+(2*4)+(1*9)=147
147 % 10 = 7
So 7787-49-7 is a valid CAS Registry Number.
