Alpha-amino-3-oxo-5-isoxazolidineacetic acid, also known as L-aspartic acid, is a non-essential amino acid that plays a crucial role in various biological processes. It is a white crystalline solid with the chemical formula C4H7NO4 and is one of the 20 standard amino acids used to form proteins in the human body. L-aspartic acid is involved in the urea cycle, which helps in the removal of excess nitrogen from the body, and it also functions as a neurotransmitter, participating in the transmission of signals between nerve cells. Additionally, it is used in the synthesis of other amino acids, such as L-lysine and L-threonine, and has applications in the food and pharmaceutical industries as a flavor enhancer and a dietary supplement.

2644-49-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2644-49-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2644-49:
(6*2)+(5*6)+(4*4)+(3*4)+(2*4)+(1*9)=87
87 % 10 = 7
So 2644-49-7 is a valid CAS Registry Number.

TOTAL SYNTHESIS OF ANTITUMOR AGENT AT-125, (αS,5S)-α-AMINO-3-CHLORO-4,5-DIHYDRO-5-ISOXAZOLEACETIC ACID

Baldwin, Jack E.,Cha, Jin K.,Kruse, Lawrence I.

, p. 5241 - 5260 (2007/10/02)

A short and efficient total synthesis of racemic AT-125 and its racemic threo isomer proceeds via an intramolecular Michael cyclization of a protected α,β-dehydroglutamic acid γ-hydroxamate.Separation of diastereomers and deprotection to racemic AT-125 followed by enzymatic resolution of the N-chloroacetamide with hog-kidney acylase provides the natural αS,5S isomer.
