Benzyloxycarbonyl-α-amino-butyrylglutamin, also known as Z-Abu-Gln, is a peptide derivative consisting of a benzyloxycarbonyl (Z) protecting group, an α-amino-butyric acid (Abu), and a glutamine (Gln) residue. Benzyloxycarbonyl-α-amino-butyrylglutamin is often used in peptide synthesis as a building block for the construction of larger peptide sequences. The Z group serves to protect the amino group of the Abu residue, preventing unwanted side reactions during peptide synthesis. Once the desired peptide sequence is formed, the Z group can be removed under mild acidic conditions, allowing for further reactions or purification steps. Z-Abu-Gln is a valuable component in the field of medicinal chemistry and drug development, as it enables the synthesis of complex peptide-based therapeutics with specific biological activities.
The CAS Registry Mumber 1170-50-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,7 and 0 respectively; the second part has 2 digits, 5 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1170-50: (6*1)+(5*1)+(4*7)+(3*0)+(2*5)+(1*0)=49 49 % 10 = 9 So 1170-50-9 is a valid CAS Registry Number.
