Z-(2S,3S)-AHPA-(S)-Leu-OBzl is a complex organic compound with the chemical name Z-(2S,3S)-4-Amino-2-hydroxy-2-phenylbutanoic acid (S)-leucine benzyl ester. It is a peptide derivative, consisting of a Z-protected amino acid sequence with a 2S,3S-AHPA (4-amino-2-hydroxy-2-phenylbutanoic acid) residue and an (S)-leucine residue, capped with a benzyl ester group. Z-(2S,3S)-AHPA-(S)-Leu-OBzl is often used in the synthesis of biologically active peptides and as a building block in medicinal chemistry, particularly in the development of new drugs and therapeutic agents. The Z-group is a protecting group that shields the amino group during peptide synthesis, allowing for selective reactions at other sites within the molecule. The benzyl ester group is used to protect the carboxylic acid functionality, which can be removed under specific conditions to reveal the free acid form of the peptide.
The CAS Registry Mumber 62058-28-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,0,5 and 8 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 62058-28: (7*6)+(6*2)+(5*0)+(4*5)+(3*8)+(2*2)+(1*8)=110 110 % 10 = 0 So 62058-28-0 is a valid CAS Registry Number.
