N-Benzyloxycarbonyl-Tyr-Ser-hydrazid, also known as Z-Tyr-Ser-hydrazid or Boc-Tyr-Ser-Hyd, is a peptide derivative that consists of three amino acid residues: tyrosine (Tyr), serine (Ser), and hydrazid (Hyd). The N-benzyloxycarbonyl (Z) group is a protecting group used in peptide synthesis to prevent unwanted side reactions, particularly during the coupling of amino acids. In N-Benzyloxycarbonyl-Tyr-Ser-hydrazid, the Z group is attached to the N-terminus of the peptide, while the hydrazid group is present at the C-terminus, making it a potential building block for the synthesis of larger peptides or as a reagent in various chemical reactions. The hydrazid group is known for its reactivity, particularly in forming hydrazone linkages, which can be useful in the formation of peptide bonds or other chemical modifications. N-Benzyloxycarbonyl-Tyr-Ser-hydrazid is often used in the field of organic chemistry and peptide synthesis, where its protecting group and reactive terminal group make it a versatile tool for constructing complex molecular structures.
The CAS Registry Mumber 2480-91-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,8 and 0 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2480-91: (6*2)+(5*4)+(4*8)+(3*0)+(2*9)+(1*1)=83 83 % 10 = 3 So 2480-91-3 is a valid CAS Registry Number.
