3401-33-0 Usage
General Description
Boc-S-benzyl-L-cysteine N-hydroxysuccinimide ester is a chemical compound used in peptide synthesis and protein modification. It consists of a cysteine residue protected by a Boc (tert-butyloxycarbonyl) group and a benzyl group, which makes it more stable and reactive under certain chemical conditions. The N-hydroxysuccinimide ester moiety is often used as a coupling reagent to react with amino groups in order to form stable amide bonds, allowing for the conjugation of the compound to proteins or peptides. Boc-S-benzyl-L-cysteine N-hydroxysuccinimide ester is commonly used in the pharmaceutical and biotechnology industries for the synthesis and modification of bioactive molecules for various applications, including drug development and proteomics research.
Check Digit Verification of cas no
The CAS Registry Mumber 3401-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,0 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3401-33:
(6*3)+(5*4)+(4*0)+(3*1)+(2*3)+(1*3)=50
50 % 10 = 0
So 3401-33-0 is a valid CAS Registry Number.

Novel Preparation of N-Protected Amino Acid Active Esters Using 1,2,2,2-Tetrachloroethyl Carbonates
Jaoudai, Mahmoud,Martinez, Jean,Castro, Bertrand
, p. 2364 - 2367 (2007/10/02)
1,2,2,2-Tetrachloroethyl chloroformate reacts with substituted phenols or N-hydroxy imides to yield crystalline and stable mixed aryl or oximido tetrachloroethyl carbonates.When allowed to react with an N-protected amino acid derivative, these compounds proved to be efficient for the syntheses of the corresponding active esters.A series of active esters including p-nitrophenol, trichlorophenol, pentafluorophenol, and N-hydroxysuccinimide derivatives were prepared by this new procedure.
