N-Benzyloxycarbonyl-L-alanyl-glycin-phenacylester, also known as Z-Ala-Gly-OPh, is a tripeptide derivative that consists of an N-benzyloxycarbonyl (Z) group, an L-alanine (Ala) residue, a glycine (Gly) residue, and a phenacyl ester (OPh) group. N-Benzyloxycarbonyl-L-alanyl-glycin-phenacylester is widely used in peptide synthesis as a protecting group for the N-terminus of peptides, which helps prevent unwanted side reactions and ensures the correct sequence of amino acids during the synthesis process. The phenacyl ester group serves as a temporary protecting group for the carboxylic acid function of the C-terminal amino acid, while the benzyloxycarbonyl group protects the amino group of the N-terminal amino acid. The use of Z-Ala-Gly-OPh in peptide synthesis allows for the controlled formation of peptide bonds and the subsequent removal of protecting groups to yield the desired peptide sequence.
The CAS Registry Mumber 6479-59-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 9 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 6479-59: (6*6)+(5*4)+(4*7)+(3*9)+(2*5)+(1*9)=130 130 % 10 = 0 So 6479-59-0 is a valid CAS Registry Number.
