Uses

Used in Chemical Catalysts:
Trimethylantimony dibromide is used as a catalyst to facilitate various chemical reactions. Its effectiveness stems from its powerful Lewis acid properties, which promote the formation of carbon-carbon bonds, a critical aspect in many organic synthesis processes.
Used in Synthesis of Antimony Compounds:
TRIMETHYLANTIMONY DIBROMIDE serves as a precursor in the synthesis of other antimony-based compounds, contributing to the development of a range of antimony-containing products.
Used in Organic Chemical Production:
Trimethylantimony dibromide is also utilized in the production of certain organic chemicals, where its catalytic properties can enhance the efficiency and yield of the desired products.
However, it is important to note that due to the toxicity and potential environmental hazards associated with trimethylantimony dibromide, strict handling and disposal protocols must be adhered to in order to mitigate risks during its use in these applications.

Check Digit Verification of cas no

The CAS Registry Mumber 24606-08-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,6,0 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 24606-08:
(7*2)+(6*4)+(5*6)+(4*0)+(3*6)+(2*0)+(1*8)=94
94 % 10 = 4
So 24606-08-4 is a valid CAS Registry Number.

A trinuclear organoantimony cation: Structure of [Me2Sb- Sb(Me2)- SbMe2][Me2SbBr2]

Breunig,Denker,Lork

, p. 1005 - 1006 (1996)

Only stable in the crystal, the title compound 1 contains the first example of a polynuclear organoantimony cation. Interionic Sb···Sb and Sb···Br contacts are observed in 1, and reversible dissociation of 1 in solution gives the starting materials Mc2ShBr and Mc4Sb2. These components exchange Mc2Sb groups in the formation of 1.

Structuren von 2, MeSbI2, und I. Darstellung von Me3SbI2 und Farbwechsel bei Me4Sb2*Me2SbBr

Breunig, Hans Joachim,Ebert, Klaus H.,Guelec, Sabahittin,Draeger, Martin,Sowerby, D. Bryan,et al.

, p. 39 - 48 (1992)

The crystal structures of the complex 2 (1) and its precursors MeSbI2 (2) and I (3) are reported.In 1 there are tetrahedral cations and square pyramidal anions with Sb-1 distances of 290-320 pm.The structure of 2 contains MeSbI2 molecules.They associate via iodine bridges to form linear chains with alternating short and long Sb-1 distances.The coordination around antimony is distorted tetragonal pyramidal.The tetrahedral coordination of the ions in 3 results in the formation of a wurtzite type structure with antimony-iodine distances of 406 and 435 pm.The novel adducts Me3Sb*MeSbI2 (4) and Me2SbSbMe2*Me2SbBr (5) are formed by reaction of the components.They decompose easily with formation of antimony(V) compounds.Crystals of 5 are yellow but become reversibly black on cooling.

Alkylantimondichloride und -bromide

Ates, Mustafa,Breunig, Hans Joachim,Guelec, Sabahittin

, p. 67 - 72 (2007/10/02)

MeSbCl2 is formed by the exchange reaction of equimolar amounts of Me2SbCl with SbCl3.Alkylantimony dibromides of the type RSbBr2 with R = Me, Et, n-Pr, n-Bu are obtained by dismutation of the corresponding dialkylantimony bromides with SbBr3.Exchange as
