L-Aspartic acid, N-[(phenylmethoxy)carbonyl]-, 1-[(4-nitrophenyl)methyl] ester is a complex organic compound with the chemical formula C19H18N2O8. It is a derivative of L-aspartic acid, an amino acid that plays a crucial role in various biological processes. In this specific compound, the L-aspartic acid molecule is modified by the addition of a phenylmethoxycarbonyl group (also known as a Fmoc protecting group) and a 4-nitrophenylmethyl ester group. The Fmoc group is commonly used in peptide synthesis to protect the amino group, while the 4-nitrophenylmethyl ester group serves as a protecting group for the carboxylic acid functionality. L-Aspartic acid, N-[(phenylmethoxy)carbonyl]-, 1-[(4-nitrophenyl)methyl] ester is primarily used in the field of peptide chemistry, where it can be employed as a building block for the synthesis of larger peptides and proteins with specific properties and functions.

4668-44-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4668-44-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4668-44:
(6*4)+(5*6)+(4*6)+(3*8)+(2*4)+(1*4)=114
114 % 10 = 4
So 4668-44-4 is a valid CAS Registry Number.

Conventional Synthesis of Thymopoietin 32-36 (TP 5) Using the 1-(1-Adamantyl)-1-methyletoxycarbonyl Group

Heinzel, Wolfgang,Kronbach, Thomas,Voelter, Wolfgang

, p. 1652 - 1658 (2007/10/02)

A synthesis of high yields of TP 5 is described.The α-amino functions were blocked by the acid-labile 1-(1-adamantyl)-1-methylethoxycarbonyl-(Adpoc)group.The Adpoc group is cleaved under mild acidolytic conditions with 3percent TFA in CH2Cl2 while the tert-butyl residues remained intact.This selective cleavage of the Adpoc group compared with the Boc and tert-butyl residues allows new strategies for the synthesis of large peptides. - Keywords: Adpoc, Amino acids, Thymopoietin
