28875-17-4 Usage
General Description
BOC-L-alanine methyl ester is a chemical compound used in the field of organic chemistry as a reagent for the synthesis of peptides and other organic molecules. It is a derivative of L-alanine, a naturally occurring amino acid, and is commonly used as a protecting group for the amino group in peptide synthesis. The BOC (tert-butoxycarbonyl) group protects the amine functionality of the alanine molecule, allowing for selective reactions with other functional groups during synthetic processes. BOC-L-alanine methyl ester is a versatile and important building block in the production of bioactive compounds, pharmaceuticals, and materials with various applications in the chemical and biotechnology industries.
Check Digit Verification of cas no
The CAS Registry Mumber 28875-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,7 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28875-17:
(7*2)+(6*8)+(5*8)+(4*7)+(3*5)+(2*1)+(1*7)=154
154 % 10 = 4
So 28875-17-4 is a valid CAS Registry Number.

Development of a temporary marker for peptides

3-[(N,N-Dimethylaminophenyl)-4′-diazenyl]benzoic acid was coupled with several amino acid esters and the product acylated further with Boc. The material thus obtained was then submitted to cleavage by electrolysis and nucleophilic attack in order to evaluate the possibility of using this chromophore as a temporary marker.
A temporary marker for biological applications
Sameiro, M,Gon?alves, T,Maia, Hernani L.S
, p. 7775 - 7777 (2007/10/03)
Having in mind the development of new colour labelled amino acid derivatives, a carboxyl azo dye was coupled to amino acid esters to give the corresponding orange N-acyl derivatives, which were in turn further acylated at their N-terminus with Boc for investigation of the conditions of possible cleavage of the chromophore by electrolysis or with nucleophiles. While difficulties were met with electrolysis owing to competitive reduction of the azo group, cleavage with N,N-diethylaminoethylamine (DEAEA) gave satisfactory results. This allows the use of the chromophore as a temporary marker.
