Trimethylsilyl--methylbromid, also known as 1-(3-(trimethylsilyl)phenyl)-1-(trimethylsilyl)methan-1-ium bromide, is a complex organosilicon compound with the chemical formula C12H22BrSi2. It features a central carbon atom bonded to two trimethylsilyl groups and a bromine atom, with a phenyl ring attached to the central carbon through a methylene bridge. Trimethylsilyl--methylbromid is characterized by its unique structure, which includes a phenyl ring with a trimethylsilyl group at the meta position, and a methyl group that is also substituted with a trimethylsilyl group. It is used in various chemical reactions, particularly in the field of organic synthesis, as a protecting group or as an intermediate in the synthesis of more complex molecules. The compound's stability and reactivity can be influenced by the presence of the trimethylsilyl groups, which can also be used to control the stereochemistry of reactions involving Trimethylsilyl--methylbromid.
The CAS Registry Mumber 26167-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,1,6 and 7 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 26167-17: (7*2)+(6*6)+(5*1)+(4*6)+(3*7)+(2*1)+(1*7)=109 109 % 10 = 9 So 26167-17-9 is a valid CAS Registry Number.
