Z-DL-α-Ethylalanin-tert.-butylester, also known as Z-DL-α-ethylalanine tert-butyl ester, is a synthetic chemical compound with the molecular formula C14H23NO4. It is a derivative of α-ethylalanine, an amino acid, where the α-carboxyl group is protected by a tert-butyl ester group, and the α-amino group is protected by a carbobenzyloxy (Z) group. Z-DL-α-Ethylalanin-tert.-butylester is commonly used in peptide synthesis as a building block, particularly in solid-phase peptide synthesis (SPPS), due to its stability and ease of coupling. The Z group is a temporary protecting group that can be removed under mild acidic conditions, while the tert-butyl ester group is more stable and can be removed under stronger acidic conditions. The combination of these protecting groups allows for controlled peptide chain elongation and subsequent deprotection steps in the synthesis process.

5105-46-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5105-46-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,0 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.Calculate Digit Verification of CAS Registry Number 5105-46:
(6*5)+(5*1)+(4*0)+(3*5)+(2*4)+(1*6)=64
64 % 10 = 4
So 5105-46-4 is a valid CAS Registry Number.
