2481-09-6 Usage

Uses

S-tert-Butyl-L-cysteine hydrochloride is a protected form of L-Cysteine (C995000), a non-essential α-amino acid that is biosynthesized in humans. L-Cysteine is also a bicarbonate-sensitive endogenous excitotoxin in rats and possibly humans.

Check Digit Verification of cas no

The CAS Registry Mumber 2481-09-6 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 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2481-09:
(6*2)+(5*4)+(4*8)+(3*1)+(2*0)+(1*9)=76
76 % 10 = 6
So 2481-09-6 is a valid CAS Registry Number.

tert-Butyl group as thiol protection in peptide synthesis

Pastuszak, Juliusz Jacek,Chimiak, Andrzej

, p. 1868 - 1873 (2007/10/02)

S-tert-Butylcysteine was obtained by a new method. A number of its N-protected derivatives and esters were synthesized. Syntheses of several peptides containing tert-butyl and acetamidomethyl or benzyl thioethers of cysteine were carried out. The tert-butyl group was removed from the thiol group of peptides by treatment with (2-nitrophenyl)sulfenyl chloride (NpsCl). The S-(2-nitrophenyl)sulfenyl derivatives so obtained were converted either into cysteine by reduction or into cystine derivatives by disproportionation. Owing to the mild deprotection conditions and the great stability of the S-tert-butyl group, the other protecting groups, particularly those of the thiols, could be easily removed from a variety of combinations.
