627-54-3 Usage

General Description

Tellurium diethyl is a chemical compound with the molecular formula (C2H5)2Te. It is a highly reactive and toxic compound that is primarily used in organic synthesis and as a catalyst for various chemical reactions. Tellurium diethyl is a colorless liquid with a distinct garlic-like odor and is highly flammable. It is classified as a potentially hazardous substance and should be handled with extreme caution. Exposure to tellurium diethyl can cause irritation to the eyes, skin, and respiratory system, and ingestion or inhalation can lead to severe health effects. Therefore, it is important to use proper safety measures and protective equipment when working with this compound.

Check Digit Verification of cas no

The CAS Registry Mumber 627-54-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 627-54:
(5*6)+(4*2)+(3*7)+(2*5)+(1*4)=73
73 % 10 = 3
So 627-54-3 is a valid CAS Registry Number.

Reaction of 1,1-dichloroethane with tellurium in the system hydrazine hydrate-potassium hydroxide

Levanova,Grabel'nykh,Kolesnikov,Klyba,Zhanchipova,Albanov,Russavskaya,Korchevin

experimental part, p. 988 - 992 (2011/02/26)

The reaction of 1,1-dichloroethane with tellurium in the system hydrazine hydrate-potassium hydroxide gave ethyltellanyl derivatives as a result of replacement of one chlorine atom in the substrate by tellurium, and of the other, by hydrogen. Probable mechanisms of reduction of the C-Cl bond and mass spectra of the products were considered. The mass spectra of ditelluroacetals revealed unusual rearrangement of the molecular ion, leading to the formation of Te-Te and new C-C bond.
