N-Benzyloxycarbonyl-S-benzylmercaptomethyl-cystein-(4-nitro-phenyl)ester, also known as Z-Bzl-Cys(4-Np)-OEt, is a complex organic compound with the molecular formula C27H26N2O6S. It is a derivative of cysteine, an amino acid, and is characterized by the presence of a benzyloxycarbonyl (Z) group, a benzylmercaptomethyl (Bzl) group, and a 4-nitrophenyl (4-Np) ester. N-Benzyloxycarbonyl-S-benzylmercaptomethyl-cystein-(4-nitro-phenyl)ester is often used in peptide synthesis as a protecting group for cysteine residues, which helps prevent unwanted side reactions and ensures the correct formation of peptide bonds. The Z group protects the amino group, while the Bzl group protects the thiol group of cysteine, and the 4-Np ester provides a chromophore for monitoring the deprotection process. The compound plays a crucial role in the synthesis of peptides and proteins with specific functional groups, contributing to the field of biochemistry and drug development.

4801-50-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4801-50-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,0 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.Calculate Digit Verification of CAS Registry Number 4801-50:
(6*4)+(5*8)+(4*0)+(3*1)+(2*5)+(1*0)=77
77 % 10 = 7
So 4801-50-7 is a valid CAS Registry Number.
