S-trityl-L-cysteine benzhydryl ester (STL-CBE) is a synthetic chemical compound that serves as a protecting group for cysteine residues in peptide synthesis. It is widely used in the field of organic chemistry and biochemistry, particularly in the synthesis of peptides and proteins. STL-CBE is characterized by its ability to selectively protect the thiol group of cysteine, which is crucial for maintaining the integrity of the peptide chain during synthesis. The benzhydryl ester group is stable under various reaction conditions, making it an effective protecting group. Upon completion of the peptide synthesis, the STL-CBE protecting group can be removed under mild acidic conditions, allowing for the free thiol group to be exposed. This selective and efficient protection and deprotection process is essential for the successful synthesis of complex peptides and proteins containing cysteine residues.

3403-36-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3403-36-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,0 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.Calculate Digit Verification of CAS Registry Number 3403-36:
(6*3)+(5*4)+(4*0)+(3*3)+(2*3)+(1*6)=59
59 % 10 = 9
So 3403-36-9 is a valid CAS Registry Number.
