"N-(O-benzyl-N-benzyloxycarbonyl-L-γ-glutamyl)-glycine ethyl ester" is a complex organic compound with the molecular formula C26H31N2O7. It is a derivative of glycine, an amino acid, and is characterized by the presence of a benzyl group attached to the oxygen atom of the benzyloxycarbonyl moiety, which is itself linked to the γ-glutamyl group. N-(O-benzyl-N-benzyloxycarbonyl-L-γ-glutamyl)-glycine ethyl ester is an ethyl ester, indicating that the carboxylic acid group is esterified with ethanol. It is often used in peptide synthesis as a protecting group to prevent unwanted side reactions, particularly in the formation of peptide bonds. The benzyl and benzyloxycarbonyl groups serve to protect the amino and carboxyl groups, respectively, until they are specifically deprotected under controlled conditions to allow for further reactions. N-(O-benzyl-N-benzyloxycarbonyl-L-γ-glutamyl)-glycine ethyl ester plays a crucial role in the synthesis of complex peptides and proteins, where precise control over the reactivity of functional groups is essential.
The CAS Registry Mumber 4124-66-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,2 and 4 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 4124-66: (6*4)+(5*1)+(4*2)+(3*4)+(2*6)+(1*6)=67 67 % 10 = 7 So 4124-66-7 is a valid CAS Registry Number.
