Z-β-Ala-ONB, or Z-β-alanine p-nitrobenzyl ester, is a synthetic chemical compound that serves as a protected amino acid derivative. It is commonly used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) techniques. The compound features a β-alanine residue, which is a non-standard amino acid, and is protected with a p-nitrobenzyl (ONB) group. This protection is crucial as it prevents unwanted side reactions during the peptide synthesis process. The Z group, or benzyloxycarbonyl group, is a temporary protecting group that shields the amino group of the β-alanine, allowing for controlled coupling reactions with other amino acid residues. Once the peptide chain is complete, the protecting groups can be removed to reveal the final peptide product. Z-β-Ala-ONB is a valuable tool in the field of biochemistry and pharmaceuticals for creating custom peptides with specific properties and functions.
The CAS Registry Mumber 53665-95-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,6,6 and 5 respectively; the second part has 2 digits, 9 and 5 respectively. Calculate Digit Verification of CAS Registry Number 53665-95: (7*5)+(6*3)+(5*6)+(4*6)+(3*5)+(2*9)+(1*5)=145 145 % 10 = 5 So 53665-95-5 is a valid CAS Registry Number.
