5256-76-8 Usage
General Description
L-Arginine 2-oxopentanedioate is a chemical compound formed from the combination of L-Arginine and 2-oxopentanedioate. L-Arginine is an amino acid that plays a critical role in protein synthesis and the production of nitric oxide, which helps to relax blood vessels and improve circulation. 2-oxopentanedioate, also known as 2-ketoglutarate, is an important intermediate in the Krebs cycle, which is involved in the production of energy in the form of adenosine triphosphate (ATP). As a combined compound, L-Arginine 2-oxopentanedioate may have potential benefits for cardiovascular health, exercise performance, and overall energy production in the body. It may also have applications in the development of nutritional supplements and pharmaceuticals aimed at improving circulation and athletic performance.
Check Digit Verification of cas no
The CAS Registry Mumber 5256-76-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,5 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5256-76:
(6*5)+(5*2)+(4*5)+(3*6)+(2*7)+(1*6)=98
98 % 10 = 8
So 5256-76-8 is a valid CAS Registry Number.

Page/Page column 2-3, (2012/04/23)
A process for preparation of α-ketoglutaric acid, which is adapted for preparing L-arginine α-ketoglutarate 1:1 and 2:1, comprising the steps of: (a) reacting methyl dichloroacetate and acrylic acid methyl ester with sodium methoxide to obtain dimethyl 2,2-dichloroglutarate; (b) reacting the dimethyl 2,2-dichloroglutarate from step (a) with hydroxide solution to obtain crude α-ketoglutaratic acid aqueous solution; (c) purifying the crude α-ketoglutaratic acid aqueous solution to obtain purified α-ketoglutaratic acid aqueous solution; and (d) adjusting a concentration of the purified α-ketoglutaratic acid aqueous solution by adding water, thereby a yield of the purified α-ketoglutaratic acid aqueous solution is approximately 75%. While avoiding the use of massive organic solvents, the process of the present invention has a remarkable high yield to realize mass production with low manufacturing cost and shortened production time.
