L-Aspartic acid, 4-[(4-nitrophenyl)methyl] ester, also known as L-Aspartic acid 4-nitrobenzyl ester, is a chemical compound with the molecular formula C11H12N2O6. It is a derivative of L-aspartic acid, an amino acid that plays a crucial role in various metabolic processes in the body. In L-Aspartic acid, 4-[(4-nitrophenyl)methyl] ester, the carboxyl group of L-aspartic acid is esterified with 4-nitrobenzyl alcohol, resulting in a molecule that is often used in peptide synthesis and as a protecting group in organic chemistry. The presence of the nitro group on the benzyl moiety makes it a useful intermediate for the synthesis of various pharmaceuticals and bioactive compounds. This ester is sensitive to hydrolysis and can be selectively removed under mild acidic or basic conditions, making it a valuable tool in the synthesis of complex molecules.

3940-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3940-63-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.Calculate Digit Verification of CAS Registry Number 3940-63:
(6*3)+(5*9)+(4*4)+(3*0)+(2*6)+(1*3)=94
94 % 10 = 4
So 3940-63-4 is a valid CAS Registry Number.
