Used in Peptide Synthesis:
BOC-CYS-OH is used as a protected amino acid in peptide synthesis. The protection of the cysteine residue is crucial to prevent unwanted disulfide bond formation during the synthesis process, ensuring the correct formation of the desired peptide.
Used in Excitotoxin Research:
BOC-CYS-OH is used as a bicarbonate-sensitive endogenous excitotoxin in rats and possibly humans. Its application in this field is to study the effects of excitotoxins on neuronal function and their potential role in neurological disorders.
Check Digit Verification of cas no
The CAS Registry Mumber 20887-95-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,8 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20887-95:
(7*2)+(6*0)+(5*8)+(4*8)+(3*7)+(2*9)+(1*5)=130
130 % 10 = 0
So 20887-95-0 is a valid CAS Registry Number.

New Amino-protective Reagents for t-Butoxycarbonylation and Benzyloxycarbonylation of Amines and Amino Acids

New amino-protective reagents for t-butoxycarbonylation and benzyloxycarbonylation of amines and amino acids have been developed. t-Butyl 2-pyridyl carbonate and t-butyl S-(2-pyridyl) thiocarbonate react cleanly with various amines and amino acids to afford N-Boc amines and N-Boc amino acids in high yields.Benzyl 2-pyridyl carbonate and O-benzyl S-(2-pyridyl) thiocarbonate are also found to be very effective in the benzyloxycarbonylation of amino acids.
