10102-20-2 Usage
Description
Sodium tellurite, a white crystalline solid, is a chemical compound with the formula Na2TeO3. It is soluble in water and is used in various applications across different industries, including bacteriology, medicine, and metallurgy.
Uses
Used in Bacteriology and Medicine:
Sodium tellurite is used as a growth medium for bacteria in microbiology. It is also employed as an effector towards the thyroid hormone system due to its similarity to selenium. Tellurium accumulates in the thyroid gland and influences the zinc thyroid level, making it a potential candidate for research in endocrinology.
Used in Metallurgy:
Sodium tellurite(IV) acts as an intermediate in the extraction of tellurium. It is used to make corrosion-resistant electroplated nickel, adding a bluish coating to iron, steel, and aluminum. This application highlights its importance in the development of advanced materials with improved properties.
Air & Water Reactions
Water soluble.
Reactivity Profile
SODIUM TELLURITE is a weak reducing agent.
Hazard
Toxic by ingestion.
Health Hazard
The material is both an oral and dermal toxic hazard. The material is toxic by ingestion. Oral ingestion of tellurium compounds is generally regarded as extremely toxic. The probable oral lethal dose is 5-50 mg/kg or between 7 drops and 1 teaspoonful for a 70 kg (150 pound) person. Tellurium compounds are regarded as super toxic for skin exposures.
Fire Hazard
When heated to decomposition, SODIUM TELLURITE emits toxic fumes of tellurium and sodium monoxide.
Safety Profile
Human poison by ingestion and parenteral routes. Experimental poison by ingestion, intravenous, and intraperitoneal routes. Human systemic effects by ingestion: coma; dyspnea; nausea or vomiting. Human mutation data reported. When heated to decomposition it emits toxic fumes of Te and Na2O. See also TELLURIUM.
Potential Exposure
Used in bacteriology and medicine. Formerly used as pesticide.
Shipping
UN3284 Tellurium compound, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
Incompatibilities
A weak reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, cadmium, halogens. Reaction with oxidizers may generate heat and products that may be flammable, combustible, or otherwise reactive.
Check Digit Verification of cas no
The CAS Registry Mumber 10102-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,0 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 10102-20:
(7*1)+(6*0)+(5*1)+(4*0)+(3*2)+(2*2)+(1*0)=22
22 % 10 = 2
So 10102-20-2 is a valid CAS Registry Number.
