N-Benzyloxycarbonyl-glycyl-DL-phenylalanin-ethylester, also known as Z-Gly-DL-Phe-OEt, is a tripeptide derivative that consists of a glycine (Gly) residue, a phenylalanine (Phe) residue, and an ethyl ester group. The N-benzyloxycarbonyl (Z) group is a protecting group used in peptide synthesis to prevent unwanted side reactions, particularly during the coupling of amino acids. N-Benzyloxycarbonyl-glycyl-DL-phenylalanin-ethylester is commonly used in organic synthesis and peptide chemistry as a building block for the construction of larger peptides and proteins. The presence of the Z group allows for controlled synthesis, while the ethyl ester group can be used for further functionalization or as a means to improve solubility in certain solvents. Z-Gly-DL-Phe-OEt is a valuable tool in the development of pharmaceuticals and the study of peptide structure and function.

5276-61-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5276-61-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,7 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5276-61:
(6*5)+(5*2)+(4*7)+(3*6)+(2*6)+(1*1)=99
99 % 10 = 9
So 5276-61-9 is a valid CAS Registry Number.

Facile and purification free synthesis of peptides utilizing ROMPgel- and ROMPsphere-supported coupling reagents

Barrett, Anthony G.M.,Bibal, Brigitte,Hopkins, Brian T.,K?bberling, Johannes,Love, Andrew C.,Tedeschi, Livio

, p. 12033 - 12041 (2007/10/03)

5-Norbornene-2-carboxaldehyde and norbornadiene were respectively converted into norbornene derivatives functionalized with fluoroformamidinium hexafluorophosphate and 2-bromo-N-methylpyridinium tetrafluoroborate residues. Both these norbornene monomers were ring opening metathesis polymerized or graft copolymerized onto polystyrene cores to produce ROMPgel and ROMPsphere peptide-coupling reagents. These were used to prepare hindered amides, dipeptides and tripeptides with minimal purification in parallel arrays.
