Uses
Different sources of media describe the Uses of 630-25-1 differently. You can refer to the following data:
1. 1,2-dibromotetrachloroethane is used as a fire-proofing agent. It is actively involved in the conversion of sulfones to alkenes by Ramberg-Backlund rearrangement. It is an effective replacement for ozone depleting solvents like dibromodifluoromethane and tetrabromodifluoroethane. It is also utilized as a brominating reagent. In analytical chemistry, it is used in quantitative determination of perhalogenated compounds by high-performance liquid chromatography (HPLC).
2. 1,2-Dibromotetrachloroethane is used as halogenating reagent for the one-pot conversion of sulfones to alkenes by Ramberg-B?cklund rearrangement. It is a useful brominating reagent for diaryl TeII species.
3. 1,2-Dibromotetrachloroethane was used in quantitative determination of perhalogenated compounds by HPLC.
General Description
1,2-Dibromotetrachloroethane acts as halogenating reagent for the one-pot conversion of sulfones to alkenes by Ramberg-B?cklund rearrangement. It is a useful brominating reagent for diaryl TeII species.
Check Digit Verification of cas no
The CAS Registry Mumber 630-25-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 630-25:
(5*6)+(4*3)+(3*0)+(2*2)+(1*5)=51
51 % 10 = 1
So 630-25-1 is a valid CAS Registry Number.

1,2-Dibromotetrachloroethane: An efficient reagent for many transformations by modified Appel reaction

An efficient and facile method has been developed for the synthesis of alkyl bromides from various alcohols under mild conditions using a triphenylphosphine (PPh 3) /1,2-dibromotetrachloroethane (DBTCE) complex in excellent yields and very short time (5 min). This method can also be applied for the transformation of chiral alcohols to their corresponding bromides in very high enantiomeric excess. The PPh 3 /DBTCE complex is also successfully applied to ring-opening reactions of cyclic ethers in mild conditions. Esterification, amidation, and formation of acid anhydrides under very mild experimental conditions are also successfully accomplished by following a modification of the Appel reaction protocol in this work.
