L-Glutamic acid, bis(trimethylsilyl) ester, also known as L-Glutamic acid N,N,O,O'-tetramethyl-bis(trimethylsilyl)ester, is a chemical compound with the molecular formula C12H30NO4Si2. It is a derivative of L-glutamic acid, an essential amino acid, where the carboxylic acid group is protected by two trimethylsilyl groups. This protection is crucial for preventing unwanted side reactions in organic synthesis, particularly in peptide synthesis, where the ester group can be selectively removed under mild conditions. The compound is a colorless liquid and is used as a reagent in the preparation of peptides and other organic compounds. It is also known for its stability and ability to facilitate the formation of amide bonds in the presence of coupling agents.

5269-43-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5269-43-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,6 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5269-43:
(6*5)+(5*2)+(4*6)+(3*9)+(2*4)+(1*3)=102
102 % 10 = 2
So 5269-43-2 is a valid CAS Registry Number.
