Z-Ser(Bzl)-Ser-NHNH2 is a synthetic peptide composed of three amino acids: N-benzyloxycarbonyl-protected serine (Z-Ser(Bzl)), serine (Ser), and a terminal hydrazine group (NHNH2). The "Z" group, or benzyloxycarbonyl, is a protecting group used in peptide synthesis to prevent unwanted side reactions, particularly during solid-phase peptide synthesis. The benzyl group can be removed under acidic conditions to yield the free serine residue. This particular peptide is of interest in chemical biology and medicinal chemistry, as the hydrazine group can act as a reducing agent or a nucleophile, making it a versatile building block for the development of new drugs and bioactive molecules. The sequence of amino acids in this peptide can influence its stability, reactivity, and potential biological activity, making it a valuable tool in the design of novel therapeutics and chemical probes.
The CAS Registry Mumber 75893-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,9 and 3 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 75893-23: (7*7)+(6*5)+(5*8)+(4*9)+(3*3)+(2*2)+(1*3)=171 171 % 10 = 1 So 75893-23-1 is a valid CAS Registry Number.
