126889-55-2 Usage
General Description
TRIFLUOROMETHANESULFONIC ACID DIETHYLISOPROPYLSILYL ESTER is a chemical compound that is commonly used as a reagent in organic synthesis. It is a silylating agent that is used to protect hydroxyl groups in organic molecules, particularly in the synthesis of pharmaceuticals and other fine chemicals. The compound is a derivative of trifluoromethanesulfonic acid, which is a strong acid commonly used in organic chemistry. The diethylisopropylsilyl ester form of this compound is often preferred due to its stability and ease of handling. TRIFLUOROMETHANESULFONIC ACID DIETHYLISOPROPYLSILYL ESTER is highly reactive and must be handled with care in a laboratory setting.
Check Digit Verification of cas no
The CAS Registry Mumber 126889-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,8 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126889-55:
(8*1)+(7*2)+(6*6)+(5*8)+(4*8)+(3*9)+(2*5)+(1*5)=172
172 % 10 = 2
So 126889-55-2 is a valid CAS Registry Number.

The diethylisopropylsilyl group: A new protecting group for alcohols
Toshima,Mukaiyama,Kinoshita,Tatsuta
, p. 6413 - 6416 (2007/10/02)
The diethylisopropylsilyl (DEIPS) group which is a new protective group for alcohols has been first characterized. DEIPS group can be distinguished from t-butyldimethylsilyl, triethylsilyl, tetrahydropyranyl groups and 2-deoxy glycoside with high selectivity in removing under mild acidic condition, although DEIPS group has high stability to many useful organic synthetic reaction conditions.
