N-Benzyloxycarbonyl-2-amino-ethanol-succinat, also known as Z-AEE-OSu, is a chemical compound with the molecular formula C13H18N2O5. It is a protected form of 2-aminoethanol, where the amino group is blocked by a benzyloxycarbonyl (Z) group, and the hydroxyl group is activated as a succinimidyl ester. N-Benzyloxycarbonyl-2-amino-ethanol-succinat is commonly used in peptide synthesis as a coupling reagent, facilitating the formation of peptide bonds between amino acids. The Z group protects the amino group from unwanted side reactions, while the succinimidyl ester group allows for efficient coupling with carboxyl groups. Upon completion of the peptide synthesis, the Z group can be removed under mild acidic conditions, revealing the free amino group.
The CAS Registry Mumber 1685-26-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,8 and 5 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1685-26: (6*1)+(5*6)+(4*8)+(3*5)+(2*2)+(1*6)=93 93 % 10 = 3 So 1685-26-3 is a valid CAS Registry Number.
